Husband and I have been having unprotected sex. We’ve both have been trying to have a baby and nothing hasn’t happened. These last few days my breasts hurt so fad, nipples are hard and constantly sore, I threw up yesterday, and I woke up this mourning going to the bathroom when I wiped I noticed this. What is it? I put a tampon in and when I pulled it out their was only a little bit of blood.
