Implantation Bleeding or Menstruation?

Ok this is odd to me maybe someone has some answers for me. I had my daughter 14 months ago I had the normal 6 week bleeding after a baby then went 6 months without a period when I did start I have been regular each month except this month I was supposed to have my period Dec 2-6 but it never came i took pregnancy tests some were undecided others negative. I started my period 12/26 it was a normal start with bright red blood but I wake up today and bearly bleeding and it's mainly brown? I'm so confused on what this is. Any help would be amazing

Hi this may be confusing but my period was on nonstop for 2 months it finally went off on Nov 20 .. I had sex on nov 22 the next week or so I went to use the restroom and noticed a spot of brown blood in my panties I thought my period was coming on but it never came.. the next week it did the same thing. I looked it up and it all pointed to implantation bleeding.. I have had a little of all symptoms.. mood swings sickness fatigue EVERYTHING.. BUT the reason I dont think im pregnant is because I dont think implantation bleeding could last this long has anyone ever experienced implantation bleeding that lasted this long my sister said I could be pregnant but I may have a possibility of a miscarriage

HELP!
Ok so me and my fiancé have been trying to conceive for 3 months now, I was on mirena for a year and we waited a month after getting it removed to start trying, I've had my mirena out for 4 months now periods have returned to normal, but still no luck! I thought maybe this month was my month, but I guess not. I started my last month on NOV 12 and bleed until NOV 16 according to the app on my phone I ovulated on NOV 27. Me and my fiancé DTD on NOV 22, 25, 26, and the 29th. I started getting super gassy around the 5th of Dec and having other symptoms also I took a test on Dec 5th and 7th both were negative. I figured I would wait and take another in two more days because my period want due until Dec 11th so I took another the morning of the 9th and it was negative also I had a couple spots on my pantry liner that were brown when I went potty mid day, well around 4:30 that afternoon I started my period or so Im think, but Im wondering and hoping and praying its just implantation bleeding since its two days before my period is suppose to come, I had just got done DTD and we noticed blood so I cleaned up and put a tampon(regular) in figuring great there goes this month but this evening when I went to go change it before bed it was only about half full the blood was more red this time though. Normally I would of filled a tampon by now and maybe had to switch to a super size. Im wondering if this is just implantation bleeding because of how light it is and since its 2 days before my cycle. I know I won't know until it other gets heavier and last the normally length or just stops, but do you momma think it couple just be implantation bleeding? HELP PLEASE.

Today is Cycle day 27, I woke w pink/red d/c, used a tampon and when I went to change it there was barely anything on it a few hrs later. (Usually as well as last 2 periods it starts w a heavier flow not spotting). Lower abdominal (I will abbreviate as abd) cramping since before thanksgiving, a couple days ago I had some sharper waves of cramping lower abd. Since then minimal lower abd cramping. when the sharper waves started I got lower back discomfort, bloating and fatigue. Occ nausea last couple days. No true breast pain, but did have some fleeting pains above breasts which reminded me of bad gas pain, but no gas. Yesterday a couple sharp pains in nipples. Cycle day 24 woke w brown d/c last half the day, nothing requiring a pad.
Oct cycle was 27 days, last cycle 35 days. So not sure when I should be expecting a period. I was planning on testing this weekend. Any thoughts would be appreciated!

I thought I would share my experience as its so frustrating when people are desperately asking questions on here and not getting any answers. So here goes. I am 35 and have a 2year old who was conceived in 4 months. We have been trying to conceive number 2 since August this year. My last proper period was on the 3rd November 2014. It was a normal 5/6 day bleed. Using " my days" iPhone cycle app knew I would ovulate around the 15th so we made sure we did it a lot around then. However my philosophy is always every other day when not on a period anyway as you never can be truly sure when you ovulate. So on the 27th November started to spot and just thought period was on its way in a few days. Spotting hit a bit heavier so stuck a tampon in and thought that was it for this month. When I was changing my tampons I noticed that they did not have much blood on them and it was more black blood than red blood. This completely stopped 2 days later. That's unusual I always have 5-7 days periods with a decent flow. On Monday and Tuesday this week I was feeling very tired and not right . Something inside me told me to get s pregnancy test. I tested on Tuesday afternoon and got a faint line. Used the other test the next day and got a faint line. Starting to get excited but wanted to be sure so took s digital this morning and got "pregnant ". I'm 4 1/2 weeks and it took me 4 months again to conceive! I am also taking seven seas "trying for a baby" vitamins for the last 4 months. Hope this helps at least someone , implantation bleeding is real and a light period which does not seem normal you should test to be sure. Good luck , Eve

I am on 26 days cycle. I had my normal period on 6/11-11/11. after 8 days on 19/11-22/11 i had another round of very dark brown to black colour discharge. I would like to know how should i determine my menstrual cycle, count from 6/11 or 19/11? I still dont have anything today. Thank you
