Going to gyn torrow?

Hi Gia ,
I think that its a bit soon too be worrying as your one and only 3 weeks late. Pregnancy would be the biggest concern for past due periods and given youve taken two test its probably fairly past the worst too say your not pregnant. Lots of things can explanation late period such as changes surrounded by diet , excercise , stress being the biggest!. Stressing just about being pregnant and individual late also counts! Try not too verbs , i also think that its best that you review how safe you are during sex so you enjoy more peace of mind in the future. All the best.
