First of all the 'withdrawal method' isnt a form of contraception so you are taking a huge risk with that alone! Also stressing out will delay your period so you really should try to relax as much as possible!! Yes there could be a chance as what you thought was your period could have been implantation bleeding but i wouldnt worry yourself until you know for sure. If your period is late then just take a hpt. I dont know whether you are wanting a baby or not, if you are then good luck, if not then i suggest you use contraception in the future to protect yourself from STIs and pregnancy!! Either way good luck!!

Quick answer: no.

Got my period yesterday... I'm much better now, thank you. And I am definitely not trying to get pregnant but good luck to those of you that are.

And I have a gyno appointment coming up soon. I think I'm ok now. Thanks for the feedback!
