Question about Preseed

Katelyn💗 • 25 years old. Married for 6 years. I have 3 sweet children, Jenna-5 and Logan-3 and Lexi- 7 months old!❤💙💜
Ok, so if I had creamy cm all month (even during ovulation) would using preseed help during ovulation? And is it safe to use after ovulation. I know some herbal supplements aren't ok to use after ovulation in case you are pregnant? Has anyone used preseed and gotten pregnant after? I am 11dpo and test have been negative and besides cramping and a little breast tenderness I just don't feel pregnant... It didn't take this long to get pregnant with my other two... Just getting frustrated... 😔
