Okay, so my last period was on July the 12th. I think it lasted for about 5-6 days...maybe 7. For almost a week now I have had slight cramping and breast pain, and a very low appetite, but when I do eat something I take a few bites and Im full and I feel like Im going to puke. This happened to me once before when I had a sinus infection. However, I had sex tonight and since then I have been in pain. Within the past hour my back and legs hurt so bad that i can hardly stand it, and im having sharp pains in my lower right and left sides, and where my breasts hurt it feels sort of like my entire chest sometimes. I dont know what this is? Can it be my period getting ready to start? I just havnet been in this much pain before a period.....plus, i was having unprotected sex, and i took an ovulation test last month and i had sex the two or three says it said i was ovulating..if that makes a difference....any advice? haha...no, it was not my first time having sex, but thats how i feel. im married....
