Its only been 8 days since me and my partner had unprotected sex. I missed my pill on the thursday night and had intercourse on the friday twice. Since monday this week I have been so nauses (sp?)like I really want to throw up but have not yet. I have also been really tired, no energy and just want to sleep. I have been feeling depressive and moody and can not tolerate much!!! It seems a lot to happen over the course of one week!!! I really dont have the cash to buy a home pregnancy test if theres no way its related to being pregnant! As well as been nauses I have been quite sore, but only when I am walking it hurts more! I have been eating more than usual aswell. Could these be signs of pregnancy? Please please help!!!
