My last period started around January 15 and lasted a few days like normal. About 5 days after my boyfriend and I had protected sex (using condoms). He did not pull out and let the condom catch the cum. Right after I had a urinary tract infection and I haven't had sex since (I finished the meds for the UTI on Tuesday, Feb. 2). My next period was scheduled to be here around Friday, Feb. 12. On Wednesday, Feb. 10 there was some discolored (pinkish/brownish) discharge in my underwear. It came in an abnormal amount than I usually get a couple days before I start. I assumed it was something left over from the UTI or just some random pre-period blood as I am 16 and not everything is completely matured (or even my recent unhealthy diet of skipping meals and junk food and soda or possibly from stress). When I took my tampon out on Friday, there was some blood mixed in with the discharged that looked like bloody snot. The discharge was still pinkish but was more clear than any other color. Then today, Saturday, Feb. 13, there has been nothing too unusual. It has been slightly difficult to use the bathroom but I'm not having to use it frequently(every couple hours like usual). My abdominal and stomach area have felt off (felt swollen as if I was on my period) and I've had cramping/back pain like I usually get before my period. I have spoken to some trusted adults who have had kids, some believe its just from stress and unhealthy eating while others think it could be the rest of my hymen releasing itself and some think I could be pregnant. I honestly do not think it's my hymen (because it was popped from being fingered) but I can't say for certain what it actually is. Could I be Pregnant? (sorry for the long entry. Trying to give as many details as possible).
