I'm 18. I lost my virginity almost 3 weeks ago (February 4) to a guy who is now my boyfriend, and it was protected, but we found out the condom broke. About a week later (February 12), we had unprotected sex twice. My ovulation day was supposedly February 9, but websites have told me different days and have also told me that I still could have been fertile on February 12. Ever since the unprotected sex I have had consistent cramps and nausea. I have had a strange food aversion to sushi, which is usually my favorite food. I have also started having cravings for pickles which I usually hate, and pizza from my university's dining hall. I tested using a First Response Early Response on February 19 and I also tested two days after that, and all of those tests came out negative. Just recently, what I thought was my period, came earlier than usual and was way lighter than usual. No blood clots, no tissue in my urine, and I only needed two pads. The blood wasn't like my regular period blood. It was the slightest bit mucousy, but mostly dry, and was a light pink color. The second day was a little bit more red, and the third day was the same light pink color from the first day. The fourth day, the blood was a little light pink but mostly brown and it seemed like it could have been the consistency of discharge. I started getting really tired the other day and even took a nap which isn't normal for me. I have also been exhausted the past week and a half and I get about 7-11 hours of sleep. And to top it off, I have had terrible cramps and bad nausea. I've also been very hungry and have put on some weight. I also started experiencing "discharge," which is more watery, about 2 days after the "period" ended. Could these be pregnancy symptoms?
