You should start using Preseed around the time you ovulate.
I hate to be the bearer of bad news, but Preseed is NOT a cure all. It simply acts as a lube that does not kill sperm (which even spit can do). If you have been on Clomid and Metformin (which is really for egg health). Then it may be time to seek out the advice of an RE.
Not saying the Preseed might not help, just please don't get your hopes up too high. I'm only saying this because I was there. I tried preseed after 4 years of trying...and nothing. I cried every cycle I used it and still got AF, because I just 'knew' Preseed who work.
I went on to
4 cycles of Clomid = BFNs
1 IUI = BFN
3 IUIs with injectables = BFN
It wasn't until I did a IVF that I was able to get PG. (8 years of trying all together)
So my advice, go ahead and try Preseed (and I really REALLY help it works for you). But if it doesn't work after a few months, call an RE. Good
