mon - 510 is my oestregen levels. oestregen rises and thats how they monitor if or when you will ovulate. usually above 1000 and LH level of 20 means you will ovulate within 48 hours.

my levels last time got to 750 then dropped, so this time when they reach 600 i go in for an ultrasound. i guess they will see if there is a follicle and check the thickness of my endometrium.

hope this has helped explain things.
