Me and my ex started seeing each other again a few days ago. I am on the pill have been for the past six months, i havent slept with no one since him as i dont wanna get in a situation of being a single mum to two. As my first child was a shock and i never really experienced the whole pregnancy thing like most parents do. But anyways we had unprotected sex just three days ago and have done it for the past three days since i had forgotton to take the pill before we started having sex but just doubled up as docs said. Does this mean im still fully protected from getting pregnant as yesterday before going out drinking i threw up but i had really bad cramp whilst i did and its never happened before and today after having sex hours and hours later i ended up having a a tiny bit of blood discharge and thats never happened either and aint due on my period for two weeks and after the first time we had sex all day i was having the urge to threw up. I do not know if he has had sex with anyone else since we split a couple months as he denys it but could this be me being really paranoid as we are in a difficult situation right now, could i be experiencing pregnancy symptoms this early or have i caught an std? I do also feel i have a really sore throat for past couple days could i just be coming down with the flu or something? Help!
