Hi Katty & to BB
Im afraid I have no advice for you regarding Fertilaid as I have never used it or even really heard of it, I just wanted to pop in and wish you good luck.
If you have been TTC (trying to conceive) for 2 years without success, I would suggest that you perhaps get a referral to see a FS (fertility specialist). You could also ask your gyn to run some tests (ie Day 21 Progesterone) which should show whether you are ovulating or not. Your gyn should have a fair idea of the tests that are relevant for you. It can take a healthy, fertile couple up to 12 months to conceive (and thats normal), so the fact that you've been trying for 2 years without success suggests that further investigation is warranted IMO (in my opinion) Hope that helps and again good luck.
