I don't know what to do? HELP!

I've been looking into getting prenatals and was considering on purchasing "pregnacare his & her conception" but have read some reviews saying it messed up the cycle for some women?

If anyone here has taken any prenatals and succeeded in getting pregnant then please do let me know which one you used. Been ttc for over a year now 💔

Also if you have any lube recommendation please let me know, we currently use pre seed but I was thinking to purchase conceive plus this time?

Our ttc journey has been full of heartbreak so far 💔 any help will be appreciated 💛
