Last month which obviously I wasn't pregnant.... Although this month....

I tried predicting my O by ten to 12 days from my last period in February. Well obviously it wouldn't have been in the 8th. It would've been anywhere from the 4 or 4th. Now obvious your not pregnant if you've missed your ovulation. Although I did start an early period. I swear it seems like a period and I'm not trying to think much of it. It started the 18th and it's stopping today. But I had clots!!! I swear it was my period... But guys..... I've been puking.. like the last three days. Two and three dpo I had severe dissiness and cramps. Now I'm 14 dpo. The bleeding is stopping but I can't even drink my coffee!! When I finish it I get really sick and not even that I had heartburn so bad last night and this morning! When I get sick it's mostly in the am. But my sore boobs just went away, and i don't bleed and have sb. But also another thing I'm very shocked and confised on is my CP! ITS HIGH SOFT AND SLIGHTLY OPEN. it's never like that before my period and not during it either. I took a test this morning and it's negative. What do you lovely ladies think? I'm 25 it would be my first pregnancy. I'm not thinking I'm pregnant. In myind I've seen too many negatives to be excited so I really don't think im over thinking. And I'm still having slight cramps with dizziness. Please help and bbd to everyone!!!! Good luck you guys!!!
