We have been not-trying (or just seeing what happens!) for 4 months now - my period is 2 days late and I'm usually very regular. I've been having cramps that feel like period cramps but no bleeding. Ive also been starving hungry all the time and I keep burping constantly 😳 I took a test on period due date but it was negative, again on day 2 of missed period but negative again! Any ideas what is going on?
