Sheeeeezzzzz!!!! Honestly, some people in the fertility business have got the most appalling bedside manner. Here we all are paying thousands of dollars for treatment and they come out with comments like "you could have had an empty follicle sack".

My advice to you is to wipe your memory of that most unhelpful and unsupportive advice. Here is a check list to confirm ovulation:

1. Pulling type sensations in the pelvic region (where the ovaries are)
2. Good clear, stringy mucus.
3. Basal body temp of around 36.2
4. Day 21 prog test of around 25-40.
5. Onset of AF 14 days after the appearance of that good, clear mucus (like to also be 14 days after your trigger injection).

I know people can have empty follicles - a friend went all the way thru ocyte collection in IVF to produce no eggs. But it's a RARE occurence. I don't want anyone here putting it on their list of worries.

OP.

PS - the corpus luteum on the follicle is where the progesterone and the hCG are coming from. On an ultra sound you can actually see the blood flow on the edges where the follicle popped.
