Open Question: Need help finding health ins. in MI with out pre-existing conditions waiting period?

Everything blue cross blue shield has a 180 day pre existing waiting period, I need help finding insurance in Michigan either without the pre existing waiting period, or at least with a smaller waiting period. It has to have maternity coverage. I already tried the esurance website. I found a couple good plans but they all have a 6 month long pre existing and I can't have that
