I’m stressing

So I should be about 8weeks and 4 days but last time I was pregnant nothing showed up till I was 3 months as I have a weird thing with my hormones. I’m scared that I could have PCOS again cos I had it about 1 year and a bit ago and I didn’t have a period for like 6 months and then it started to hurt. What should I do? I really want there to be a baby but I’m scared maybe it’s PCOS! I’ve had no bleeding and all the pregnancy symptoms? Any suggestions?
