Ovulation Predictor

I have a question maybe ya'll can help clear up. I have been doing the ovulation predictors (pee in a cup). It showed a LH surge Sunday..and has showed one since then- (today is Wednesday). How long is the surge suppose to last? Hubby and I have been getting busy since then. But I'm wondering when the best times is?-It says 24-36 hrs after the first surge...but since  it's kept going I'm wondering If we need to keep doing it. (I think hubby is worn out)

thanks!

I've read that after you get the first surge that you don't need to test anymore. But, I've also heard if you test in the morning it can be a false positive. Can I ask why you kept testing after the first?

I got my first smiley face detection this past weekend  on CD16, so I hit Google right away lol. I read a lot of conflicting stuff, but essentially I got this....12 hours before an LH detection and up to 48 hours after.

So my plan for next month since I now have a rough idea when my surge might be is to start BD'ing every other day starting CD11, then every day starting on CD 15 until I get my positive OPK (and then whenever possible after that). I know they say sometimes it can be too much, but right now we don't know DHs count so we're going to go all out next round.

The directions said to test in the morning. I kept testing to make sure it wasn't a one time fluke thing. And I wanna know if my surge is 2-5 days long? It can happen apperantly. But how long is too long?

 Are you using Clearblue Advanced OPK's?? They require FMU and show you four fertile days, first with a blinking smiley and then with a solid one.

I spent some time researching multiple positive OPK's and here is what I gather. OPK tests only tell you that your body is preparing to ovulate, not that it actually will. So, you cannot confirm your O date based on a positive OPK.  What it does tell you is that you might ovulate within 12-48 hours following the positive. So...it would make sense that if you picked up your surge, and tested again 24 hours later, that you'd still get a ++ if your original test was picking up the beginning of your surge. How close together were your positives?

My OPK kit said to test in the morning too, but here's what I found in some research:

LH is synthesized in the morning so first morning urine is not the best time to collect samples for OPKs since it may not appear in urine until the afternoon. Ideally the best time to test is after 10a.m. to early evening. So if you get a positive OPK in the morning you may already be nearing the end of your LH surge.

Generally O takes place within 12-48 hours after the test is first detected (using afternoon samples). Once you get a positive you are at peak fertility.

This is why BD’ing 12 hours before your positive OPK could be beneficial. Say you test at 8a.m. and it was negative. Your body might surge at 10a.m. and now you get your positive the next morning, essentially you could have been surging for 22 hours already.  Sperm can survive days, but ovulation only has a small window. So, I would think BD’ing any time during fertile days should increase your chances. The more swimmers the better. ;)
