I need help understanding OPK testing. We are TTC

[BMead18]

My recent period was just this: Spotting pink June 27th, June 18th I began a light bleed of bright red until June 30th, then I had spotting of pink July 1st and it stopped. We had sex on these days up until period: June 25th, 26th, 28th, 29th, 30th and 1st because it was so light and my app claimed I was in my fertile window during the 23rd to the 28th which kind of explains the intense amount of cervical mucus I experienced but I'm unsure of whether this is possible prior to getting my period officially the 29th. We then had sex July 2nd, 3rd, I spotted a little on the 4th, had sex the 5th, 7th and 8th so far. I am now CD 11 today and my period track is claiming my fertile window starts tomorrow the 10th. Which we will be having sex again.

All OPKs I have taken so far have given me the following results: Light T line around 9am, Kinda dark around 12-1pm and then dark but not as dark or darker than Control line when I do my evening testing at 6pm. I started testing on CD5 because of my extremely short period. I also stopped my birth control 2 weeks prior to my period. Now, I know I'm testing alot, I was just trying to get a feel of everything to see how different they are by the day and time I take them. I have since opted into only testing at night for now.

Now, when normally do women get their peak positive opks? When should I test at night to get an accurate as it can get result?

I do have PCOS but I am testing with OPKS before I even consider temping.

Also, by having sex before - during and as frequent as we have recently, could this still increase our chances in possibly conceiving this month even if I miss testing and see my surge or stop testing too early and may miss the surge completely because of the fact? I know sperm can last up to 5 days. This is why I am curious.

Ugh, I am sorry.  I had a hard time follow this.  Here is the best way to get pregnant . . .  first, yes.  sperm lives up to a week.  So, on cycle day one which is the first day of your period . . .  you start counting and then on day 10, begin having sex every other day for the next 10 days.  If your cycle is longer than average, continue the sex every other day thing for 4 to 10 more days.  (a lot of sex, but hey, that's not all bad).  This should catch the egg.  I had trouble reading body signs such as cervical mucus and found ovulation test kits to be hard to read as well.  So, this is the best method.  good luck
