So my boyfriend and I had sex on December 31st and again the first week of January, but I can't remember what day it was exactly. We didn't use a condom either time and I'm on birth control and I have PCOS. My last period was from December 22-26 and I've been having some weird pains in my upper belly and that same area has been feeling like it's tightening for the past 2 or 3 days. I've also been taking a nap around 2 or 3 in the afternoon for the past few days because I've been so tired, which I don't normally do. I've been getting up at least once or twice every night for the past few days to go pee, which isn't normal for me. I haven't taken a test yet because i don't wanna possibly take one too early. I don't know when my next period is going to come because my PCOS messes up my schedule. Could I be pregnant? Any advice is appreciated!
