As someone who has endomitriosis I was concerned that I would have issues getting pregnant, wanting to understand how my system works after iud removal I purchased proov so I'd understand my cycle first. Was the best investment i could make . After iud removal and waiting for my next period cycle I was able to work out I had estrogen dominance and low lh / progesterone so I worked on my diet accordingly. Next cycle round my numbers were great and I got pregnant! I highly recommend this product to anyone who is ttc and is either curious to how your system is functioning or having issues with trying. The team were super helpful and when I emailed I'd get a response:)
