I'm on my 3rd week of taking Levora and I was suppose to get my period a couple of days ago. The first week of taking it I would take it in time everyday but the second week I would be a couple hours late to take it because of my crazy work hours. We did not use a condom once and I took plan b the next day cause I wasn't sure if my birth control would work because I took it late for a couple of days. I was suppose to get my period a couple of days ago. Should I be worried? I'm having some cramping and other period symptoms I normally get but no period.
