My early preg symptoms

Me and my S/o were TTC and we got pregnant! Around 2 weeks before my af was supposed to arrive I started having af like cramping off and on until around 4-5 days before Af was supposed to show I was ABSOLUTELY POSITIVELY CERTAIN I was about to start my period I was having cramps that felt EXACTLY like af was making an appearance, I was having moodswings like a MF (very abnormal for me) and I was having diahrea (tbh probably something I ate cause my whole family had that) my first pregnancy symptom was definitely my breasts! They were more sensitive. I thought I was crazy I'd sit there and rub my nipples noticing how sensitive they were! (only when stimulated at first) my breasts have never really been sensitive. (I've always had a bigger chest though)
