Questions. TMI

So last summer my husband and I started TTC for our first. In August my dr started me on Metformin, I didn't realize at the time that she thought I had PCOS, and didn't find that out til I went back until November. I ended up having an ultrasound to check on my uterus. No cyst, but the small string of pearls started.

I have been on Metformin sense and have had 3 regular periods for the first time in my life thanks to progesterone.

Now for the questions. If yall can help.

1. Just because I've had normal periods does that mean I AM ovulating?

2. Does the medication mess with my chances of getting pregnant.

3. I have a smaller uterus and one ovary is smaller than the other will that effect my chances in anyway?

4. Just bc I have PCOS does that mean I HAVE to go to a specialist to try and get pregnant, or can it happen naturally?

5. I have started a diet & exercise regiment bc I am overweight and have issues losing weight. What's my best option to manage my weight?

Thanks for your help.
