Question about Preseed.

Stormy • Stormy, 29 🌻 Divorced. Baby #1 born 4/19/18 after 19 months TTC with tubal insufficiency! Baby #2 born 01/26/21 after issues with ovulation and an incompetent cervix.
Is it still okay to use preseed if you have plenty of EWCM? This is our first cycle using it. Used it last night and tonight. Positive OPKs. Fingers crossed.
