When would you start to use a ovulation predictor kit?

Question

Ive never used one before, but some friends are telling me to try them and see what kind of results I get. Like on what cycle day would you start using them on?

Answer 1

If you are like clockwork, here's a chart for you to use to find what day to start testing:

Cycle length 21 days, start testing Day 5
Cycle length 22 days, start testing Day 5
Cycle length 23 days, start testing Day 6
Cycle length 24 days, start testing Day 7
Cycle length 25 days, start testing Day 8
Cycle length 26 days, start testing Day 9
Cycle length 27 days, start testing Day 10
Cycle length 28 days, start testing Day 11
Cycle length 29 days, start testing Day 12
30 days, Day 13
31 days, Day 14
32 days, Day 15
33 days, Day 16
34 days, Day 17
35 days, Day 18

If your cycles tend to be irregular, calculate the average using the last 3 cycles and then use the chart.... or, just start testing on CD 05 and keep going (you'll need more than one kit to do this). Remember to start having sex daily when you start testing. A positive reading means that ovulation is 24-36 hours away, so you want to have sperm already in there waiting for it.

The best time to test is 2 p.m. or as close as possible. Anytime between noon and 8 p.m. is fine, first morning urine is not recommended. The reason for this is that most women experience a surge in the morning, but it can take 4 hours for it to show up in your urine, so you want to be sure to catch it on your test.

**Make sure to test at about the same time every day**

Good luck!!

The usual guideline is to consider your last six months of menstrual cycles, take the shortest cycle and start testing 17 days before that.

For example, suppose your last 6 cycles were 28 days, 26 days, 32 days, 30 days, 29 days and 30 days. Take the shortest cycle-26 days, and subtract 17 from it. 26-17=9. Count the first day you have actual bleeding, not spotting as day 1 of your cycle, and begin testing on day 9 of your cycle.

Why 17 days? Ovulation happens for most people between 10 and 16 days before menstruation. OPKs look for a surge in LH (lutenizing hormone) which peaks between 12 and 36 hours before ovulation.

It depends how long your cycles are. Luteal phase, or time after you ovulate before your period starts, is typically 12-16 days. If you have a normal 28-day cycle, you probably ovulate cycle day 12-16 (day 14 is average), so I would start using the OPK cycle day 10 to be safe. If you have a longer cycle, you probably ovulate later than day 14 and if you have a shorter cycle, you typically ovulate earlier than day 14. There are typically 7 sticks in a box, so you should have enough as long as you don't test too early (ie I wouldn't start testing on day 10 if you have a 35 day cycle).

Answer 4

seems such as you're having intercourse at precisely the nicely suited time. i grew to become into utilizing a regular sort ovulation kit, and it grew to become into constructive for 3 or 4 days besides, which grew to become into puzzling. So I switched to a ClearBlue digital ovulation attempt. It shows an empty circle in case you're no longer ovulating, and a happyface in case you're :) It grew to become into much less puzzling. For the 2nd component of your question, i do no longer understand if that's important to have intercourse regular. My hubby and that i attempted to because of fact we figured, the greater possibilities the greater efficient! some human beings say the different day regardless of the undeniable fact that. good success. :D
