I last had sex on Feb 14, it was the first time I had se w no condom, just trusted my pill. I’ve been having really bad headaches so I decided to take pregnancy test 3 weeks later and tested negative. on Saturday morning I had a sore throat n went on ab my day just like normal. However at night time after I had something to eat I instantly started throwing up and it went on up until yesterday, Sunday morning. I woke up fine today. I’m just wondering if I should take another test. Could this be a stomach bug or did my throat infection have anything to do w it?
