Not too sure.

So me and my boyfriend went on a road trip for 8 days from 24th June 2nd July. We drove 5 hours to see his mom and step father, it was great. And as you can imagine they still had work, even though we were there and that meant a lot of alone time and sexy time😁. I don't even think I can estimate the amount of times we got at it, but anyway. I am on the pill so we don't worry about condoms, but I still haven't had my period for July; she was meant to arrive on 4th July. I have been having the usual cramps but no bleeding what so ever, was just wondering if anyone else on the pill had a side affect like this or should I do a PT??
