Someone help. I need some good advice on what too do. Me and my partner have been having sex almost everyday now for 3 weeks. I've on the pill and and take it every night at 8. My last period was 3 weeks ago as well. I've been having unprotected sex with my partner and he's been cumming inside me every time. We had sex every day for the past 5 days straight and I missed my pill last night..on top of all that. After visiting my obgyn Doctor about 2 weeks ago she came to realization I wasn't having my period during the right time of the month. Instead of me bleeding during the last cycle/last week of pills I was having menstrating during the 2nd or 3rd week of my pack. She said that wasn't right... This all sounds confusing ;( my next period is supposed too be in 6 days should I wait and see if it comes and if it doesn't take a test or take one now??? When you you start having symptoms?? I have a major increase in my sex drive as well as some nausea.
