I took the pill (rigevidon) on the first day of my period which was also a week before going to my boyfriends. We then had unprotected sex multiple times. After I came home, I came off the pill. A few days after I was bleeding for about 3 days which was around the 16/17th of August. A month later (now the 20th) I still havent had my period. Im having small cramps/pains around my stomach/vagina area which I sometimes get when im about to come on. Ive had this for a few days but still havent come on. Ive been searching for any answers on the Internet. I dont want to be pregnant.. Im scared.
