Help ladies

Hello ladies. I had ovulated 2 days ago and also had sex 2 or 3 days prior to ovulation. I took an ovulation test and it showed positive. Now it’s 2 dpo and I’ve been having horrible cramps all morning right underneath my belly button by my scar from my 1st pregnancy. Yesterday and today I have eaten so much more food then I normally have and just feeling overall burned out. My stomach is hard to the touch. My nipples are a little sore. And I’m peeing a lot. I also smoke cigarettes but now anymore the last couple days I can’t even finish a cigarette without getting sick to my stomach. I know it’s too early for a test but do you possibly think this could possibly lead up to a BFP? Please no rude comments just needed to get it off my chest. Help? Please?
