Estrogen surge before ovulation symptoms

It’s not necessary to test yourself every day (or multiple times a day) until you get a positive result. The tests can be expensive to use that frequently.

Ovulation usually occurs about 14 days before your period.

Your LH surge occurs a day or two before that. So knowing how long your cycle is (from one period to the next) will help you figure out when to start testing.

For example, let’s say your cycle is 32 days between periods. Day one of the cycle is the first day of your period.

Ovulation most likely occurs around day 18.

You should get a positive result on an OPK a day or two before that, on day 16 or 17.

It’s a good idea to start testing every day (or every other day) in the morning a few days before that, around cycle day 13. This is to make sure that you catch the positive result, in case you have a shorter cycle that month.

Once you get a positive result, it’s time to start trying.

Most experts recommend having sex two to three times over the next 24 to 48 hours.
