Reset/lutenyl... does anyone recognize this?

Hi, I've been reading along on various topics for the past few months but haven't found my story anywhere. Maybe you guys can help me out. We've been trying for a baby for about a year now, but unfortunately, it hasn't gone as smoothly as hoped. Meanwhile, my sister-in-law, nine friends, and five colleagues have all gotten pregnant or given birth without any complications... After ten years of taking the pill, I stopped taking that mess and ended up with quite long cycles (40 to 45 days), but I comforted myself with the thought that at least I had something. However, in January, my period stopped completely. After three months, I went to the GP who did various blood tests. Everything was super, except for my progesterone, which meant I apparently wasn't ovulating. She also thought I was a bit overweight (75kg for 1m70) while I really didn't feel that fat. She couldn't do anything then and I had to wait. It wasn't until the sixth month that I was allowed to get medication. So in the following months, I started walking, since I was already eating healthily anyway. So now in July, I weighed 69kg, but unfortunately, I still hadn't had my period. I then got Lutenyl from the GP. Take one pill for 10 days. I really felt bad on those pills. Now we're about a week after the last pill and I did indeed first have some brown discharge and now two days of light period. The GP hopes that I'll get 'reset' with this and start making my own cycles again. What do you think? My partner and I have Christmas in mind as the next date (because I do that too, thinking 'by then I'll probably be pregnant'... But I actually have a bad feeling about it. And I know that compared to many, I maybe shouldn't complain, but without ovulation, it makes me so discouraged...
