right before i pms i get sore boobs primarily in the nipple area, i had unprotected sex for the first time about a week ago, and now my boobs are really sore on the sides and tops which is unusual for me. I have also been experiencing other early signs of pregnancy like fatigue, more frequent urination, sharp twisting pains in my ovaries, and a couple others. i dont have a regular period to know when the best time to take a pregnancy test is either. any suggestions?
