Okay so............ Opinions?

I need opinions on what you guys think. So obviously it's way to early to test as I am only going on 3 dpo. Me and my husband have sex daily. Every single day. Not a day goes by that we DON'T fuck. 😉 lol okay but anyways. We don't do anything to prevent pregnancy. We already have a son and wouldn't mind another. We aren't technically TRYING but we also are not doing anything to prevent it If that makes sense?? ANYWAYS, on Thursday, I had really bad cramps, stabbing like pains in my lower abdomin traveling down thru my vagina. On Friday (aug.19) I had little pains, enough to know they were there. And I also got a MAJOR MIGRAINE like to where I was crying cause how bad it hurt, I was super dizzy, and I fell when I stood up cause how dizzy I was and my vision completely went out. Also aug. 19. (Still have the migraine as we speak) when I got home from work today, I took of my bra (relief😍😥😌) and my right nipple was super sensitive and hurt a little for like 3 seconds then went away. THAT'S NEVER HAPPENS, and also to mention, I NEVER GET CRAMPS OUT OF NO WHERE. The only time I do get them, is on my 2nd and 3rd day of my period then it goes away. Do you guys think I could be pregnant?

P.s. the last time I ever had a migraine like this was when I was pregnant with my son. I had them everyday literally
