What is going on??

NV

Okay so I have no had a period in 5 months. I’m not pregnant so far but I’m currently ttc. Well my SO and I had sex 12/28 and now we’re waiting well. That night/ next morning I was getting mild cramping. Didn’t know why. So I just ignored it. Well the beginning of this week my nipples started getting super sore and sensitive. They currently still are. It’s not my boob, not so much the Areola part, just the nipple. Just the slightest touch and it hurts. I figured maybe my period was coming out of no where because I also got some mild cramping as well. But I’m not sure if it’s possible I could be pregnant or my body is just fucked up lol. I don’t wanna buy a pregnancy test just yet because I always get disappointed. I’d appreciate some advice 😊
