I've been on birth control (Junel FE), taking it regularly like I'm supposed to. I had sex and didn't use a condom but I did take a Plan B pill within 24 hours. This is the third day of no period (sometimes my period takes one or two days). I did recently move and my sleeping schedule is messed up as well, I have been stressed, and I currently have an ear infection which has caused swollen tonsils so I couldn't eat or drink for the past few days and because of that, I was practically bedridden. I just started antibiotics yesterday. I tend to get extremely paranoid so I would like some reassurance please.
