BD during LH Surge/Deployment Struggles

My LH surge started yesterday and we BD about 2 times yesterday and 1 time early this morning before he went on duty. Today is my ovulation day so I’m freaking out that we can’t DTD even more and to make matters worse, he leaves back for Deployment in less than a week. 😭 I got my Nexplanon taken out in April before he left the first half of the deployment and we got hit with a BFN. When he came back in July, he came back RIGHT AFTER my Ovulation Day and yet ANOTHER BFN, and here we are in August, trying to make magic work before he leaves in a few days. Please send MEGA baby dust my way!! Also, do you think the chances are hindered even though we did have sex once a day until today
