Thread: Every month I get the same paranoid feeling.

I'm 19, and have been sexually active since I was 18. I've had mostly normal periods, I'd get them about 20ish days apart and it was consistent so I didn't worry. But recently, for the past few months they've been lighter and a little later than usual. Last time I got my period, I went a full month after that with no period, then got it on the 1st of the next month, and on the 20th had another light period that lasted like 3 or 4 days. And it looks as if it's going to be the same this month, because it's nearing the end of the month and I have not had a period this month yet. Last time I got a brown discharge before I got my period that smelled bad, and now I had it again. Should I expect my period soon? I've had unprotected sex with the pull out method but not for a few months, every time I have slept with my partner in the past two months has been with a condom. Is pregnancy a likely possibility here?

I find myself getting worried about this every month now, because my sister has a baby that I take care of and another one is just out of the question right now...I have been ready to go on the pill but was waiting until a regular period to start taking it after.
