My period is due today, but it hasn’t shown up. I’m usually like clockwork 27-28 days cycles. I taken three easy at home tests and they are all stark negatives at 11dpo/12dpo/13dpo. Has anyone had something similar. I don’t know if I should just get a FRER or just wait a couple of days for my period. I’ve been cramping off and on and a like heavy feeling in my like cervix. Any advice?
