@bunnylovesbear: I checked CM to decide when to start testing.

Do you know how long your cycle usually is? If so, take the average, and start checking 17 days before that number. (ie your usual cycle is 31 days, so 31-17-14, start using OPKs on CD14. Probably won’t get a positive one until 3-5 days later, in this case CD17-CD19.

 

But easier to use CM as a guide.

Take them in the afternoon, I have the best results at 2pm.

The test line has to be the same colour or darker than the control.  You will get a line for the majority of your cycle, but they really do need to be exact.

You can get a positive for 2-3 days. 

Not everyone sees the line get darker and fade out.  Some get definite negatives and then see them turn positive the next day.

@bunnylovesbear: No, you shouldn’t use your morning pee, because the LH surge usually happens in the afternoon. Most everything I’ve read suggests testing between 2pm and 8pm, with a 4 hour urine hold, or as long as you can hold it. I try not to drink anything for those 4 hours, to concentrate my urine, and also so I don’t have nearly as strong an urge to pee. 

My period usually lasts 4-5 days, and I start testing on day 10 of my cycle. I usually ovulate on day 14 or 15, so I start a little bit early, but I have a big bag of the cheap Amazon ones, so I can afford to use as many as I want. The month I got pregnant I was glad I do test early, because I O’d on CD11. Had I waited longer to test, I would have missed it.But I have them to spare. 

Good luck!

My best advice is to test twice a day (morning and afternoon).  My LH surge seems to start at varying times and only lasts for like 24 hours so if you don’t do it every 12 hours you could miss it.  I use digital tests in the morning and wandfo tests in the afternoon (and then confirm it with a digital if positive).

I always start testing on day 10 of my cycle.

I use them in the afternoo/early evening.  I start testing the day after AF only bc after getting EWCM early one cycle I had a feeling I was going to O early and I was right but would have never known unless I tested.  Hope this helps and good luck!

Thanks for the advice girls. I’ve been using the cheapo OPKs for the past few months to get a handle on when I ovulate but I’ve never seen a truly dark line. I think it’s because I drink too much water and my urine is too diluted. I’ll try again with less drinking water before I want to test.

This is the month my husband REALLY wants us to get pregnant after two months of failure. I think he’s been secretly hoping I don’t get pregnant until this month because he didn’t want the birth to come during the school year.

@brianneG- Have you tried the digital tests?  They are more expensive, but in my view more reliable.  I have a hard time reading the Wandfos.

@winniewolf: I really don’t want to spend the money on the digital tests but I might if we’re still not pregnant after six months. Getting pregnant is basically just a hobby for us right now since our emergency fund isn’t really strong enough to handle a baby. He really wants a summer baby AND $20,000 in the bank. Unfortunately, we can’t quite afford to save $2K a month unless my work picks up soon.
