Help! When should I BD this cycle..

Hailee
I fear that glow could be off, even though with last months period, & predicted ovulation day, I took OPK & it was positive. So when would be a good time to start BD? We obviously BD all the time, and  I've been taking geritol & evening primrose oil, & bought preseed to use. BF actually takes prenatal vitamin gummies because they taste good, but i just don't know when to incorporate preseed in or to stop taking geritol & primrose as I've heard to stop once you ovulate...  😂😂😂
