So i am 16 days late today, the predicted period date is usually on point, very few times has it been just a few days off. I've taken a test and its negative so now im like whats going on. Do i wait a week to test again? Ive seen post of women testing postitive before their missed period. We been trying for about 3 years now, we have 1 daughter who will be 8 in March. I had the iud in for 5 years right after her and i also had a miscarriage a year prior to having my daughter. Just confused and lost idk what to do. Has anyone else had anything similar?
