Would i be pregnant if me and my boyfriend had sex and he pulled out and cummed on his hand and in his pants and then 10-15 mins later we had sex again but only for like 30 seconds and neither of us have finishes?

Risk: You could get pregnant from what you did. If this happened less than 72 hours ago, take Plan B. Three weeks after sex do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions carefully. If you do not wish to be pregnant, use contraception all the time, every time. Wish you good health!
