not much CM???

Ok so since my miscarriage I noticed that I'm not having much CM when I'm suppose to ovulate before I had a lot and I knew exzactly the days leading up to O and the once I had now I barely notice anything there this is the second time since the miscarriage I am wanting to TTC but I usually go by my CM so I'm not sure how to tell I don't like using OPKs because I've never gotten a actual positive had anyone gotten pregnant with little CM????
