I need to breath.

Me and So had an oopsies during my ovulation. Im trying to relax my brain and let it know that theres no point worryinh untill AF is due. Not for a week and a half. By the time realized the oopsie it was too late for plan b. I mean aside from having to move we will be fine finacially. I could even givw my so 16or more of my 35week parental leave (as it would be our fourth) that leave me with 29weeks plus 15maternity so I would go back when the baby is 9ish months. I have adhd and cant stop my brain from obsessing over the unknown untill i know for sure.....it sucks. anytips?
