I have been feeling moody lately and on edge, my breasts/nipples have been tender for 3 weeks now (some days worse than others), I have gas like all the time, I've been getting cramps (like hardcore menstrual cramps) after sex about half the time, my appetite has been weird, and my sex drive has gone down a little. I have PCOS (Polycystic Ovarian Syndrome), so I know i probably have infertility problems, but is it possible that I am pregnant? I took a pregnancy test 6 days ago and it said negative. But that was 10 days before my period is supposed to start. My tracker says I have 4 days left, but is it possible that I could be pregnant? (Even though I haven't had any morning sickness or nausea)
