<s>[INST] I had my fist sex couple of days ago. We used condom and he ejaculated inside me with condom. Two days afterwards my breast started to hurt. Although my period should be in few days, and I checked the condom afterwards and it wasn't leaking, I am frightened that I can be pregnant. Is there any possibility? Thank you [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
