My period was due today, I’m on cycle day 35... Hasn’t started today. I’ve had irregular periods, but the last 4 months or so have been pretty regular. I am sexually active and we use the pull out method. For the last 5 days or so, I’ve been getting super nauseous after I eat certain foods and I’m tired (but that’s nothing new). I took a test on Sunday and it was negative. I know periods can be off by a few days, but what would you guys do? 🧐
