OPK & DTD Help please

[Sesamechick]

Hi all,

So with all the apps I have, predicted ovulation dates were 17th, 18th, 19th and 22nd (!!)
Anyways, we DTD 15th & 16th. We were away 17th, 18th and back home19th and couldn't DTD as we were sharing a room with the kids. I left my OPK strips at home so had no idea, although I had EWCM on the 19th (DH too exhausted to DTD on 19th)
Anyways today I took 3 OPK tests at different times and the last 2 are both peak and quite clearly positive (pics attached)
My question is when best to DTD? Tonight, tomorrow and Monday?
Did DTD on 15th & 16th give me a chance or do those 2 dates not count?
Thank you so much!!!

Sperm can live in the body for ages, something like 5 days or so. The 15th and 16th are within that time range so should be OK
Your egg will live for 24 hours so theres still a chance of catching it if you're quick
Otherwise, should be OK. Fx and baby dust!

@NatGee
Thanks for your reply!!
I'm hoping if we DTD tonight and tomorrow it will increase our chances.
FX and baby dust to you too xxx

Picture attached of my OPK tests.
We DTD last night (20th) and hope to DTD tonight (21st)
Praying..... X

You likely are ovulating today, going by later pic. Just DTD the next few nights to raise your chances!

@startfresh
Will definitely try. For sure tonight...
Really want this to be our month.
Thanks xxx

So I know time will tell but any opinions on whether we are in with a chance?
DTD 15, 16, 20 & 21.
Planned the 22nd too but DH on antibiotics and wasn't feeling well.
Thanks x
