I was trying to get pregnant for 3 months now I decide to use the ovulation kit. Got a LH surge and had sex for 2 days after. What are my chances?

Up to 20% - 25% At 22 most couples can get pregnant in the first 6-12 months of trying. You have up to a 20-25% chance per month if both partners are healthy, and an 85% chance of getting pregnant in a year. See a fertility specialist (rei) for help if you get close to the one year mark, or sooner if you have known problems like endometriosis or previous pid. Best wishes.
