Found out I have PCOS today

So I found out I have PCOS today, my periods have always been irregular but since stopping Breastfeeding my daughter I haven't had any periods..
I had an internal ultrasound on my ovaries & bloods & I have PCOS..
Did any of you get pregnant multiple times successfully with pcos?
I fell pregnant within 3 months of trying with my daughter without knowing I had PCOS. But now I know I have it I feel stressed & not stopped crying..
We are TTC no2 now. & with any periods it's difficult 
Any tips or help
I have around 45lbs to loose with I know is not helping
