I took an ovulation test on Jan 27 because on here it said I should ovulate it came back I was not ovulating, but just in case we had intercourse several times a day from the 27-29. Then on the 29 I took another test due to pain in my side and it said I was at my peak. We were still having sex multiple times the 27-31. Could the test be wrong? Did I ovulate late and still have a chance to get pregnant? Has anyone else used these with luck?
