I had missed my periods from 24 days. N had unprotected sex at 18 april but my husband did not ejaculate inside me. And agn had sex at 26 april but this time I took unwanted 72. Ryt now I am having pain in my lower abdomen, weakness n vomiting daily. I had not done pregnancy test bcoz I cnt do it due to some family problem. Well I hve tried some homemade test too which were negative. I do not want to conceive now. At d same time can not get help from family member. please suggest me what should I do to avoid pregnancy. I evn have kidney stone problem. Is my period is effected by stone problem. M confused. Plzz help Doctor. Plzzz.
