 [ Symptoms ] do i have to wait till a missed period to tell if i am pregnant  i had my period 1 week ago last night we had an oops i would like to find out as soon as possible if i am pregnant because i am on an anti depressant that should not be taken while pregnant i do not want to stop the medicine for 3 weeks if this is just a false alarm we do not have 50 bucks to go get a day after pill  that sounds pathetic [ Disease ] the only advice that i can give you is to have your son see a medical professional someone who can take a detailed medical history perform an examination and order some essential diagnostic tests there is really nothing that can be done blindly over the internet to get to the bottom of this complex issue as a concerned parent see that it happens
