I am 32 and have 3 children. I am not on any birth control and my periods are always on a 28 day cycle. They are always heavy with a lot of clotting and last between 4-6 days. On 4/2/12 I started what I figured was my period but it was really light. My husband and I also had sex the same day with a possibility of an "oops." I prepared for a heavy flow with a pad and it didn't get anything on it all day. I only had blood when I wiped. It wasn't as light as spotting but I have never had such a light period. The next morning it was pinkish brown when I wiped. Halfway through the day it was completely gone. I never had that happen before. I did a bunch of searching online and it sounded like implantation bleeding. I didn't want to freak out so I said I would wait until my next period to see. Now I did notice that I didn't have any cramps or tender breasts at all this "period(?)," which is strange because I also get really bad cramps and sore breasts every month. That was actually really nice for a change. The day after it was over I started having sort of period-like cramps for 10 days straight with no period. I was about to call the doctor because it was so weird, but then it stopped. On 4/28/12 I had spotting no cramps or sore breasts. One time I wiped and it was very small amount of pink tinged with just a little bit of brown streaks. It was only one time that day and one time the next day 4/29/12. Then nothing else until about 1 pm the next day 4/30/12. I actually went to WalMart and bought a pregnancy test and as I was walking out the door to leave and I felt the period starting feeling. So I haven't used it yet. I am now having that really light flow period like I had on 4/2/12 but have some cramping now. It is 5/1/12 and still having this really light period. All of this is very unusual and I have never ever had anything like this before. I was excited for a minute thinking I might be pregnant (even though I am not really trying to get pregnant) but now I am worried something is wrong "down there." Has this happened to anybody else? Any advise? I have a doctor appointment later this week but I am worried.
