Advice

Looking for some advice. It's been a year and a half and no pregnancy. My husband just had his sperm tested and everything was good. The doctor said it was probably my fault we haven't conceived yet. I have had my hormones tested all fine I do have protein C deficiency and some fibroids. I get my period regular. I am in 500mg Metformin once a day. Since starting that I finally have had some positive ovulation tests but my last cycle nothing...I have left a message for my doctor about wanting to start clomid. Is there anything else I should be doing? Its overwhelming 😔 I'm only 30 both of my sisters who are younger have had no problems having kids.
