I just got off of my period on the 16th of July and had sex the 18th 20th and 21st. I’m really scared that I’m pregnant yesterday it was 3 weeks since had sex with my bf. This week I’ve being having mood swings and I’ve been very emotional. Yesterday I woke up very nauseous and sick to my stomach my body was very hot but I was freezing I had a really hard time sleeping but I was so tired. I took two tests one was negative and one was positive so these signs show that I might be pregnant?? Please comment anything helps!!
