Help??

Okay so ive gotten a couple of faint positives, but trying not to get my hopes up. I’m cramping very bad and it makes me nauseas sometimes. ITs similar to when AF comes, but I’ve been feeling this way for a while and no AF?? And my left boob hurts so bad. Like my nipple area hurts... kinda like when you do a very deep upper chest workout. But righty is completely fine! Is this normal?
