protein powder and bfp?

Curious if anyone has heard of a link between protein levels and fertility? After trying to conceive for over 4 years for baby #2 we FINALLY got our bfp and I've been racking my brain trying to think of what was different and the only thing I can think of is that I started drinking a high quality protein powder in shakes the month before and month of conceiving and I'm wondering if it's actually possible that it's to thank for our sweet pea. Wondering if any other Mommas have experienced this? Just want to do some research that way we can hopefully have an easier time with our 3rd little blessing some day 💜 Baby dust to all!
