A little hope or suggestion

Hello ladies!!! I'm 26 and TTC with my first. I am starting 2000mg of metformin Dr orders and going and picking up Vitex Agnus Castus. I have spent the last two days researching and gathering every piece of information that I can. I was diagnosed with PCOS when I was 15 and have never had a regular period unless I was on BC. I have been off BC since 1-20-15 and no period since. I'm hoping that starting this metformin and Virtex will help me to ovulate and help me on my way to getting the BFP!!! I have heard lots of positive things about these two combos, has anyone one else had luck with this combo??
