When to see a Fertility specialist ?

When do you think a good time to see a Fertility specialist is ? Been ttc for almost 2 years. Had lap surgery last December 2014. Miscarried on April 28th( worst day of my life) . Had 3 periods that were pretty normal and regular after that. This last period I started spotting way early, like a week and a half before period was due. And really painful cramps all over.

I have now been going to get acupuncture for infertility and endo and taking warm cycle tea pills. I have gone in once a week for the last 4 weeks. Was really hoping to be pregnant this month......but no just started spotting dark brown again this monday. Should I keep getting acupuncture for a few more months before seeing a specialist? ?? Would really like some advice.
