took plan b twice last month because I was worried because the guy I had sex with was a bit rude about using a condom and I think he took it off halfway. Anyways, I took Plan B on the 12th oc October, got my period the next day for about a week, then took Plan B after I had sex with him again around the 19th, received a period again for 5 days. Now its been about a month since then and no period. I took 2 pregnancy tests, one last week and one Monday and both negative. Could I possibly skip a period because I took Plan B too much?
