I started taking Fertilaid on cd1 in February. I am now cd27 with low temps. This is unusual.Should I continue Fertilaid the second month?

Isn't fertilaid a homeopathic treatment?

Nothing of this sort is guaranteed. Continue to take it if you wish, but with charting, etc. you may not need the extra help. If you've been trying for aprox. 1 year, I would suggest scheduling a pre-conception appointment with your doctor.
