Resuming sex post partum.

Sarah
Hi ladies! My daughter is just shy of 2 months and tonight for the first time my husband and I tried resuming sex since having her. My doctor gave us the green light but I was pretty reluctant. Well, mid nookie I felt a pain and had him stop. After checking myself I found a little blood. Any other mommies out there in a similar situation right now? I'm scared to try again, but more so I am feeling like I am failing as a partner.
