35 and fertility testing after 2 children years apart

Me and my DH have been TTC actively for months now... I haven’t been on BC since my 6 year old was less than 1 (except for a month almost 2 years ago when the MD recommended it for abdominal pain).

So last month when I thought we did everything to make it happen, including an ovulation test that was positive... I got my monthly “enemy”! I was in tears and I called my MD and got in that day! She recommended several fertility tests... blood work, sperm count, HSG, transvaginal ultrasound, more blood work, and now a uterine biopsy.

I just read her email response on the tests... sperm count “normal”... HSG remarkable, uterus normal size and Fallopian tubes clear... but the blood work I had 2 days ago shows that I didn’t ovulate this month... and my male hormone DHEAS is elevated and the ultrasound showed thickening of the endometrial lining. I’m beside myself, she said it might be PCOS...

I was for sure that after all the “normal” test results that this month would be it! I was going to refuse the uterine biopsy because I was afraid if I was pregnant it would harm the fetus.... now I’m just feeling defeated!

I know some of you are trying for your first and it makes me feel so selfish! I have 2 sons... 19 with a previous relationship and 6 with my DH... I really want more... but I’m feeling tonight maybe I should just throw in the towel and be happy I have what I have and just move on from all this testing and possible taking hormones... 😢... thoughts??
