You might be ovulating late in your cycle. Last cycle of mine was 35days long and I ovulated on CD20. So I think by this weekend you would be ovulating. Do make him come inside you every time.
Btw have a nice and safe trip to Ohio. All my good wishes are with you for a fresh start.
I wana POAS so bad but it'll only come up negative as I'm only 7DPO.
BD in a car is fine! Done it plenty of times
