So i had unprotected sex about a month ago. I am not on the pill and recently i have been very tired the odd time i am nautious and my nipples are verrrrrry sore and sensative as well as my boobs, and they feel like they have grown like a full cup size!! i took two test but both came up negative. is it possible i am pregnant and its just too soon to tell? I did have my period but i had it last time i was pregnant as well. my mothers the same way she had her period with all 4 times she was preganant.
