Have I missed my chance??

Rachael

Hey ladies, need some advice - I’ve had 2 miscarriages this year (when I wasn’t really “trying”) but now we are properly trying for our baby. However I’m worried I keep missing my window! My husband is in the military and often leaves for work at short notice, and recently he has left a day or 2 before I get my positive OPK! We do BD during the days leading up to it, so what are the chances the sperm hang around enough to catch my egg a few days later?! Any advice would be amazing!
