Good evening. To get right to the point, I am freaking out about the possibility of becoming pregnant after sleeping with a guy last night I ve been seeing. We had sex twice. The first time he used a condom, however I m not sure if he did because I didn t check. The second time, he did not use one, (which was honestly a mistake). I told him to not cum inside me, and he said he wouldn t. However I am equally unsure whether he did or not. Later I asked him again, and he promised he was very careful. I am on birth control, however some days I forget to take it at 2 pm, so I end up taking it a few hours later. I also think there was one time this month I forgot completely one day, and took two pills the following day. I am due to get my period either tomorrow or Tuesday, and to say the least I will rejoice if I get it. My question is, what is the likelihood of getting pregnant with these factors? Thank you.

Hi. Good to see your concerns about your health. So far as your question is concerned lets first discuss some basic concepts. First ovulation occurs exactly 14 days before the start of bleeding regardless of the length of cycle and an ovum remains viable for a period of 24-48 hours in female reproductive system. Next is if you are on a regular birth control pill and if you forget to take pill on one day then taking two pills on next day can compensate. Keeping in view these few basic points it can be said that there is a minimal chance (almost zero) of you becoming pregnant. Your dates are expected in a day or two, so my advice is just sit back and relax. If menses occur that's great otherwise you should visit a gynecologist for confirmation of pregnancy and further planning and management. Wishing you best of healthRegards
