Hi, I had my period last on the 27th of Dec, I am usually on the mircolite tablet but was late starting it by two days, I started on the 2nd of Jan instead of the 31st of Dec. Due to other problems not related I may have forgotten to take a few more inbetween when i was on tablets for my stomach. Like clockwork I would get my time on the thursday of the seven day break which should have been thursday last, but its now sunday and I should be starting a new tablet but still no period. Could I be pregnant ?
