i had unprotected sex stupid me the week i was supposed to get it..he did finish in me. I took 4 tests and they were negatives..did i take them too soon? could my hormone levels be low? although i have been experiencing nausea without vomiting and tender breasts.. what do you think. help me! just want to know if you can get pregnant if you have sex the week of your period without actually getting it and being irregular pill pills for the past year
