I had unprotected sex with my boyfriend on 14th april and had an ipill the same day. My period cycle begins on 5th of every month. I was very regular. I had some bleeding after consuming the ipill for 2-3 days. Today is the 17th and I haven't had any periods since the whole month. I took 2 pregnancy tests but they were both negative. Is there a possibility of me being pregnant? I have sore breasts and I'm very tensed. Please suggest what should I do?
