hi! Im 5+3 and me and husband didn't use an ovulation kit as we wanted it to feel as natural as poss, if that makes sense! i just calculated 1st main ov. day ( 14 days from 1st day of last period) and we had sex 3 or 4 times on these days lol. I know that sounds a bit extreme, and even though we also heard that too much sex can lower sperm count, we thought to us, it just felt like we were missing out on baby making time, and every second counted!
We just put music on and tried to be romantic and be as relaxed as poss. we managed to conceive in the 2nd month and i think its just because we had told ourselves beforehand that it would take ages and we didn't think about it toooo much ( although its hard not to!)
so i think making time to put on a nice tune, eating well and being as relaxed and romantic as poss when you want to make a baby stands you in good stead! i remember we had bon jovi on and its kinda nice thinking you probably conceived to a specific song! makes it even more special.
So my opinion is, just do what feels right for you!
Good luck
