Help please...

My husband and I been ttc #1 for 7 months now. And was sure this month was my month. Period was due on the 5th. Ovulated the 25th. My periods are usually pretty regular. I've had all the "typical" symptoms of early pregnancy and no sign of my monthly friend showing up. But I took a clearblue advanced digital test this morning and I got a BFN 😳

I'm getting so discouraged.

I'm convinced it's my husband, as bad as that seems...I've been pregnant before with a previous partner but has a miscarriage. So I know I can get pregnant. But he's also had a couple partners all unprotected and there was nothing. He won't go to the doctor either...all I want is a family. I'm ready to give up. Please help.
