My progesterone level is 5 on day 20 of 34 day cycle. on other cycles it wasn't more than 3. so does it mean i am going to ovulate?

Recheck: With a 34 day cycle you would ovulate on about cycle day 20. The progesterone level increases after ovulation so you may be checking a bit too soon to see the rise. It may be more informative to check the progesterone level on cycle day 27 to 30. By then, if you have ovulated it will be elevated and if you have conceived it will even be much higher. Good luck.
