So I had unprotected sex on the 26th of October and I took plan B on the 27th. Everything was normal I had a mild stomach ache and a tiny bit of spotting. On November first I started to get a weird brown discharge which eventually turned into blood on the 2nd. It was definitely more than spotting but not as heavy as my regular period, It is now the 4th and I am back to brown discharge. Do you think this is from the plan B? I was supposed to get my period on the 11th of November, so should i expect to get my period again at that time too?
