Sudden PCOS onset while trying for second baby?

Hello there,

I am looking for some advice. I just turned 38 and I have a 2.5 year old daughter. We have started trying for a second baby about 10 months ago (last June). I weaned my girl off last February and have had super regular periods my entire life. I used to be one of those who was never even a day late, but I'm aware our bodies aren't machines and we need to be kind to ourselves. But that's just a sidenote. Either way, I had regular periods throughout the 1.5 years of breastfeeding and conceived my first baby within 2 months of trying.

Then, I suddenly missed a period last June, but I now know it was a Phantom Period with all the symptoms but now blood. Scary enough. However, I missed one again in January, same thing. I got an ultrasound scan and the doctor told me I had one polycystic ovary and a little fibroid in my uterus, but apparently, neither was "an issue"?

I know things can change, but I am baffled by this diagnosis and all of a sudden, I had a weird 2 weeks bleeding instead of a period in March and am now experiencing my 3rd Phantom Period without any blood. This is super scary and I am so worried I won't be able to have another baby ... I know I need to get my blood tested but I have no idea where I am in my cycle now with all the fake periods and odd bleeding. Has anyone had a similar issue? I was wondering if it is some kind of delayed post-weaning problem? I'm getting a private scan next week and I'm arranging my blood tests too, but I was just wandering if I am the only one with "out of the blue" PCOS / perimenopause (?) like that? Any advice on how to continue this weird journey will be greatly appreciated <3
