Didn't follow doctors orders.

Miscarriage started April 29. Stopped bleeding a couple days ago. Doctor advised a checkup that all was closed but she recommended using a condom until my next period so that my lining is thick enough. Well hubby and I decided tonight was the night to Bd for the first time and we didn't use a condom. I didn't tell hubby, but I checked my CM right before and it was super stretchy, like EWCM. I'm not going to dwell on it, but I'm wondering if I just caused myself to be on the path to another miscarriage.
