What is the pregnancy risk of dry humping?

If you suspect there is a high chance of pregnancy, I would suggest repeating the urine pregnancy test in a week’s time. If it still negative then it is unlikely you are pregnant. Irregular bleeding like what you describe is not uncommon in PCOS even in the absence of pregnancy. I would recommend using contraception if you are sexually active. In addition to preventing pregnancy, contraception like the oral contraceptive pill (OCP) will make your periods regular and light, and prevent endometrial hyperplasia (build up of womb lining) which is very common in PCOS.

Hi, depending on where you are in your ovulation cycle, there is about a 20% chance of getting pregnant from unprotected sex. Ie for every 100 fertile women who have unprotected sex for a month, 20 of them get pregnant. You are more likely to conceive if you have unprotected sex during the middle 2 weeks of your cycle. You will have the highest risk of pregnancy by having unprotected sex 1 or 2 days before your ovulation starts as per the infographic below, when the ovary releases the egg. In your case, the risk of pregnancy is lower as your partner did not ejaculate.
