My boyfriend and I have been having unprotected sex pretty much every day since August 11th. On August 21st I out of nowhere got severely nauseated to the point of almost throwing up and I never have done that before. I didn't get nauseated after that. Fast forward to August 26th and I'm nauseous from like noon to 6 every day with cramps on the insides of my hip bones. Certain things smell gross to me and certain foods I used to love make me want to gag. I don't know when I should test? I tested a few days ago and got a negative. Forgot to mention that I have very irregular periods so I'm never sure when I ovulate or when I'm supposed to get my period.
