Okay, I've been doing a lot of research online about this and I just feel like I am not finding an answer, so here is what I am trying to figure out! My boyfriend and I had sex during my period last month, and it basically stopped my period (it was also unprotected) & this month it was a few days late but when it started, it was a light pink color - last 2 days, and then it turned to a light brown color - and its been 4 days and its still been light brown on and off though.. I've been wearing panty liners. In all the years of having a period - I have NEVER had a period like this, can you please tell me what's going on with my body!

Possible, infection, STD, pregnancy or other causes.

Just this information alone is not enough to go back.

Rule out pregnancy about 10 days to 2 weeks after this last period, do a pregnancy test with first urine of the morning.

If Neg, and not corrected by next period, see your doctor

You won't find the answer online, no matter how hard you search. You will find many possible things that could be going on, but you won't get a diagnosis, not without going to a doctor.

It's possible that you're pregnant. It's also possible that you're just having an off month, have an infection, have a tumor, etc. etc. etc, and really, the possibilities are too vast to write down.

Try a pregnancy test using first morning urine. If it's negative, wait until your next period is due. If you miss it, or it's not a normal period, then test again or see your doctor. If you feel worried about this then there's really no harm at all in seeing your doctor now.

Good luck.
