I wanted to jump in here as it sounds like a few people are in the same boat.
My husband and I have been trying to conceive for six months now without success. Through tracking, I noticed that I had a short luteal phase and blood tests recently revealed that while I am ovulating regularly, I have low progesterone levels. I am planning on starting a whole30 ASAP to see if I can help balance my hormones. I am very nervous about the whole thing because I currently have an extremely regular cycle and I am worried that the whole30 will render the next 30 days useless as it will likely alter my cycle. I have done a whole30 previously and I bled/spotted for much of it.
I will be tracking my cycle with the OPKs so we will see how this goes.
Best of luck to everyone!
