Ok so I had unprotected sex a week before my last period which was 3 weeks ago. My period came normal as usual. Four days ago I had unprotected sex again. But for the past week and half I have been feeling sick all the time mainly at night, had diarea, stomach pains that feel like I'm being punched and it hurts when I lay on stomach. Now I haven't missed my period so I don't think I'm pregnant but just curious. We are trying for a baby so fingerscrossed. But with my having a period and not missing last one I'm not sure.
