faint line after miscarriage

Amie
Hi Ladies, 
My husband and I had an early natural miscarriage on December 31st. We decided to not prevent, but not try either as we were waiting for our next cycle to start. It's been 5 weeks now and still no signs of AF. I took this test this morning, not with FMU. There is a definite faint line! I'm so scared, but trying not to freak out too badly. I haven't mentioned anything to my husband yet because I don't want to get his hopes up. Praying for this miracle. 🙏🏻  Has this happened to anyone else? Any insight would be appreciated!
