Trying to get pregnant

So me and my boyfriend have been trying to get pregnant. Well my periods are so irregular that I don't get my period for a little while. Well I was suppose to start my period soon and I've been having bad cramps but I haven't started yet. I know this is 50/50% chance but I've been cramping really bad for like a couple weeks and i know you can cramp really bad in early pregnancy so maybe just maybe? Ive been praying really hard. I have such baby fever. I don't know what to do anymore. I just wanna give up trying. 😩😩
