Okay so me and my husband are trying to get pregnant my last period started April 8th and ended April 12th , we had unprotected sex on the 23rd and I got a positive on my ovulation test the next day 24th and have been feeling little cramps since yesterday ,is there still a chance I could get pregnant? We can't have sex often due to it takes him awhile to build up his sperm so we only did it that one time
