Plus size and starting my clomid journey!

I'm a plus size girl who is borderline pcos. I haven't had success conceiving because I'm not ovulating. So dr has decided I should start clomid. I was going to try to lose some weight before starting the clomid. I'm a size 18, and would ideally get to a size 10. But I know that would take soooo long and I'm scared I won't be able to do it. I had one obgyn shame me on needing to lose weight and possibly being a high risk pregnancy. Then a second opinion dr said my weight isn't even likely to cause problems at all. I feel like trying to conceive while plus size adds so much extra stress and pressure! 
Anyways, 
Just took my first Aygestin pill...10 days, then a period, then I start Clomid on day 3-7. 
I'm so nervous! How will my body react to the drugs? Will I ovulate? Will I get pregnant? Will I possibly have multiples? Is miscarriage a possibility? All these fears and questions running through my mind!! 
I feel nauseous, and I'm not sure if it's the Aygestin or my anxiety!!
I know so many of you have gone through this and have had the same worries. 
Anyone want to share your Clomid experiences? Advice? 
Baby dust to you all ❤️
