Needing advice about baby #3

Lexie

So currently we been trying to get pregnant for baby #3 I am currently taking a supplement called pregnitude and I when I first started I had a period but now I’m not, I don’t know if it’s because I keep switching between pregnitude and Conception for her pills, I did start off with pregnitude and had a period then I stopped when I didn’t have anymore and I went on conception and had a period and now that I switched back to pregnitude I don’t have a period and I’m 5 days late I did ovulate but I took a test and it was negative for pregnancy

I don’t know if I just messed up my period or if I’m pregnant or just not having period because of stress. My last period was April 1-April 7 my ovulation was supposedly 20th of April but we only did the deed on the 11th,14th,and 18th which was 2 days before my ovulation day any advice of what I should do,

Does anyone else know any other fertility supplements i can take that will help with ovulation and periods to successfully get pregnant that worked for them
