There is a high probability you are! The doctors don't usually want to intervene until you have missed your next period. I had sex with my now ex partner 3 different nights in only a couple of weeks when he was here over 3 months ago and i am now expecting mine and his second baby!! Plus i was on the pill!
Best thing to do is wait till next period, on the other hand, maybe you should make an appointment with the doctors.
its highly likely but you wont know until you test.
Some tests can work 3 days before your periods due. Theyre called first response and available in chemist and many supermarlets.
