I’ve read that if you have a chemical pregnancy, you will get your period a week later than expected. Is this 100% true? AF is due today for me...I conceived and got a faint positive Wednesday’s and even lighter 2nd line Thursday and barely visible line Friday. I started spotting brown Friday and today seems like AF is right on time and starting off slow with dull cramps and discomfort. Anyone else have a chemical and start bleeding when AF was expected or did yours come a week late like I’ve read on numerous articles?
