What is going on?

Hey guys, I don’t normally post anything on here. But my period is late and I’ve been cramping. And my nipples have been super sensitive lately. My boyfriend barely have sex so I don’t know what it is. I know it’s possible that I could be pregnant but I’ve been really doubting that I am since we’ve been trying for a few months now. If anyone could help shine some light on my situation it would help a ton. Thanks in advance guys.
