Starting vitamins + supplements soon.

Splurged on Amazon with prenatals, supplements, and OPKs. I already know the deal with the OPKs; this'll be my 2nd cycle with them. But the vitamins and supplements... When do I start? Our first insemination will probably be at the end of June (or early July if my cycle shifts between now and then).

Prenatals: VitaFusion Prenatal Gummies - ETA CD1

Supplement: Upspring Fertility+ (maca, cohosh, and shatavari) - ETA CD-5

I was originally thinking start both on CD1, since they'll both be in by then, but I am open to advice.
