hi we made mistake on 8th july and immediately after 5-6 hours i took morning after pill. I am having my regular period cycle 20 days and it is continue. I did 2 home urine test and one at pharmacy and one blood test at doctors office all negative. recently in october i did vaginal sonogram and no pregnancy. i don't have any pregnancy system. After that incident we never did sex. I heard about cryptic pregnancy and worried a lot. Please confirm i can make sure i have no problem.
