Scared and need advice please.

I have PCOS and my husband and I have been ttc for a year now. My periods were always irregular but about seven years ago, they hit like clock work. Usually lasting three to four days, start to finish. I was due for AF on 4/17 but I started spotting on 4/14. It was full blown by the next day with horrible cramping and (sorry tmi) over the course of the seven days I had it, I lost multiple big clots. I've never had this happen before. I usually lose a couple here and there but not that big. They were the size of a golf ball. It slowed and stopped on 4/19 but I started spotting later that day and has continued to the point today that I had to put on a pad. I'm still cramping pretty bad too. Idk if my PCOS is getting worse, if I'm developing yet another female condition, if I possibly miscarried and didn't know I was pregnant, or if it's just a change in my cycle and I will go back to normal next month. I have an appointment with my OB tomorrow but I'm scared. My husband and I want nothing more than to be parents and I feel like I'm slowly losing any ability I may have. I feel like I'm failing my husband who has been tested and is above average 😢 Has anyone else had this? Success stories? Failure stories? Thank you for reading and I'm sorry it's so long of a post.
