What could change menstrual flow from heavy to light, mid-period?

I normally have a heavy period, that lasts for about 6 days. I am on the 3rd day right now, and my flow suddenly went very light (it was heavy for the past two days, like normal). I'm 18 and have had my period since I was 10 and it's been regular and very predictable for the past year or so. What could cause the sudden change? I did get the TDAP (tetanus, diphtheria and pertussis) vaccine yesterday, that's the one thing I can think of that has been different with me lately, other than maybe stress from school... could either of those cause such a dramatic change?

Hi Anon!

If your question is about pregnancy then you can't be pregnant since you have your period. The flow of periods can be slow and heavy or light so that has no bearing.

Hello,

My husband and I have been trying for baby #2! Our daughter is only a year old. My last period was on February 18,2016 then the next was March 20th, 2016. we started trying for baby number 2 on April 13, 16, 18, 21, 22. On April 21 I had a clear stretchy discharge. April 25 I took a pregnancy test was negative, later that day I got my period. Started light then went heavy that same day. I had clots and everything. 2rd day it was still heavy and i was starting to get cramps which I couldn't tolerate. 4 day my period got light to the point I thought was done then like 30mins later I figured it wasn't gone since I wiped and it was very light. I have cramps, I'm bloated and feel very uncomfortable, I am also very emotional , feel very tired, I'm gassy, and im having a hard time falling asleep. My period usually last 7days and no clots no cramps. I still feel like I could have a chance of being pregnant, I actually feel pregnant... But I don't know , I want to get a pregnancy test but I'm scared of another negative. Do you think if I test today or withing a week I might get a slight positive?

Hi Anon!

Thanks for your post!

Do you understand your cycle in terms of ovulation etc. If you had your period on March 20th and tried for a baby from April 13th on, you would have completely missed your fertile window for pregnancy.

You need to start trying for a baby within about 9 days of the start of your cycle. The first day of your cycle is the first day of your period so that would have been around March 29th and then through about April 7th or so. By the time the 13th came around, it would be far too late to start to try, your ovulation time would be long gone.

Your period and the symptoms are an indicator that you are not pregnant. A test can confirm this for you - and will answer your questions for you far better than I can! It does not sound like you are pregnant - start trying again in the next few days, do not wait for two weeks.

Good luck, I hope you have some good news soon!

Hello,

Curious if you were pregnant, I am experiencing very similar symptoms. The orange-like coloured period, no but everything else plus lower back pain. We're you pregnant? I see this post is a bit old.

Thank you!

Hi I am 14 and I got my period at 12 and it has always been heavy and now is lighter than usual. During the course of this year my period changed from flowing for 7-8 days and now 5-6 days not only shorter days but I have had nausea and other side effects. So what does it mean?

Hi Anon

This likely means your cycle is regulating itself over time due to your hormones changing during puberty. Your cycle may change in the next few years too. Then you may see fluctuations as an adult until your 50s when everything changes once more and you enter menopause. But for the most part your cycle should be pretty regular as an adult.

Best,
Susan

I use an iud. I tend to have extremes heavy periods even before I was on birth control. I normally cramp a couple days before my period starts but my cramps hurt really bad this time. I use my period tracker and my period came a day later than the tracker. Started off with red dots than brown spotting but when I wiped lots of red blood. Today I'm bleeding a little more but not as heavy as normal and I'm still cramping pretty bad. Still red blood when I wipe just not on the tampon. Is this normal? I have been a bit more stressed than usual and not eating as much.
