Dr. Hanif warmly Welcomes you!
Thanks for consulting at my virtual clinic. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns.
Less chances of
pregnancy, if he didn't actually ejaculated inside ,completely.
But to be on the safe side (if you miss the periods) go for
hCG urine test from a laboratory. It will help you keep calm.
But usually in circumstances you told in history, there are less chances of getting pregnant. It may be the premenstrual pains and cramps that you are feeling. I prefer to recommend you not to take
Ibuprofen or NSAIDs for pain, as it will delay the periods and you will wrongly take it as pregnancy.
Hope it helps. If you need further, detailed and quick assistance related to any health issues in future, feel free to 'ask me a question' directly from my profile.
Have a wonderful time ahead.
Best Regards!
DR. MUHAMMAD M. HANIF
