My husband and I have been having unprotected sex but I’m supposed to be ovulating now and the next few days. We had sex three times in the past week and a half but for some reason I’m having a lot of cramps and today I felt like throwing up. Are these early signs or impossible? I took a test (14 days early or so which I know isn’t the time but tried anyways and it says not pregnant) are these signs too early for pregnancy and it’s probably something else? Please help 🙏
