okay.. I had sex on my period in october and my period in november was really messed up. i bled a lil bit then it turned to dry blood and then it did it again and then i stopped after 2 days.. I have been have signs. like my boobs are really sore and tender my nnipples are a lil darker. i have bloating like a pregnancy shape belly, and cramping.. my feet and lower back hurts. and i get neusea a lot through out the day.. and pee more than i have been.. What does that mean??
