It started off  6 months ago where my girlfriend took these tablets to help the pain from her periods but as the weeks and months went by she noticed that she was gradually getting later and later and the last 5 times shes been late 12 days at the most.

This time she is late (as expected due to her tablets) but she is much later than she has ever been before! She's 16 days late and we're both starting to panic.

Yes we are in a sexual relationship but I have always made sure that I have been using protection and we've always been as careful as possible to make sure than no pre-cum would get anywhere and we've never touched each other when theres been cum involved

Is there still a chance that she could be pregnant?! Need help!! Please comment!!
