Had unprotected on the 18 through 22nd of last month, was seeing my period when I had the first postinor2 and had another one on 22 , on 26th, started bleeding which ended on the 4th day. Last week till now, I have pimples on my face, even on my ear and if I walk for a long distance, my vaginal itches me. Are thes due to the drug? Is there something I should do stop it? This is my first time of taking it
