I had my period almost two weeks ago. I have had unprotected sex before and after my period. I am irregular sometime I don't get my period for many months then it comes with only having three days. Lately I have been feeling sick (my throat feels sore), and after my period on July 10 my nipples started to hurt although my period was as heavy ad it usually is. I'm having more cravings for food lately, and I'm having lower abdominal pains on and off ( that started with the sore nipples) My finance and I have been trying for a baby for the past year, and so far no luck. I'm very scared of what is happening to me if anyone can explain that would be great!! Thanks
