12dpo Testing with Ovulation strip

Hi Everyone! Im around 12 dpo, we had DTDed 3 days in a row during O time and I got a positive of the strips and Clear Blue (purple ovulation test). The last 3 days I have tried 2 pregnancy test strips and a normal digital clear blue, all have come out negative even though I have been feeling gassy, getting a couple of sharp pains and feeling like AF is starting since we DTD.

Today I decided to randomly do an ovulation strip and surprisingly it is positive test line (same darkness as the control line). Does anyone know what this means? My AF is due in a couple of days.

It is not unusual to get a positive OPK just before your period starts.

While you can use OPK as a pregnancy test after a missed period, if you're getting negative pregnancy tests then your positive OPK is NOT indicative of pregnancy.
