Is this the surge I'm waiting for!? Advice !!!

I've never done the ovulation tests before but thinking this is what we've been waiting for, right? Does this mean I'm ovulating now or will be ovulating? Do we have sex everyday till the lines lighten? (My husband wants a baby so much that he wants to do it 3 -4 x a day lol). It's been 4 months ttc and ironically.... today is the due date that I should have been having my baby girl that I lost at 20 weeks in Nov so it's a very emotional weekend for us. Praying this is the month we can try pregnancy again and not lost this one. Also been taking the pregnancy prep, vitex and have used preseed this month with hoped the techniques will work!!!
