Question

If I start my period around the 21st or 22nd,When should I get my LH SURGE or OVULATION ?

Answer 1

Jen is absolutely right. Count back 14 days from when you expect your next period to start and that's your most likely ovulation date. You should get your LH surge in the 5 days before that date or up to 2 days after it, if you're on a regular cycle. If you're more irregular, you might find it comes earlier than you think and in that case you should simply start the OPK sooner.

Answer 3

it depends on how many days your cycles normally are.  you ovulate 14 days BEFORE your next period.  if you start your period on august 21 for example, that means you ovulated on or about august 7.
