I had sex 3 days ago. Could I be nearing ovulation or if this left over semen from 3 days ago?? I know my opk are not positive yet but the first pic is from 1pm this afternoon and the bottom opk test is from just now. I have been drinking a lot of fluids today so that possibly why its not as dark as first test. AND YES, I KNOW the test line has to be darker or dark as control line. But I have stretchy cm. Please help. Near ovulation cm or left over semen from 3 days ago?
