Infertility ttc

Ashley

My husband and I have been ttc for a year and a half. I ovulate but no pregnancy. Has this happened to anyone else? I went to my doctor and he says to lose weight but I know that isn’t a factor. Should I go to a fertility specialist? And if so can somebody please tell me the costs and what to expect. I’m losing hope here and I need any tips! Currently taking vitex and inositol
