Y’all, I know I’m not crazy. For the past week I’ve been so nauseous and so sick. And this morning actually started throwing up. I FEEL pregnant but keep getting negatives. I went to ob this morning and she did one urine pregnancy test and said you ain’t pregnant, idk what it is, and called me on some acid reflux medicine And I don’t even have acid reflux.😓 my last period started on July 24th. I read online where you can be pregnant and have no hcg till way later?
