I need all the baby dust!

I am plus size.. I want to be pregnant & become a mother more than anything! My husband and I have been trying for about 3 years. I haven’t been to the OB in a few years. So do I just tell the doc that we haven’t had any luck ? Or how do I bring it up? I know women larger than me have had successful pregnancies with clomid. I’m just so desperate. I’m making myself crazy. I just need successful clomid stories from plus size 290+ women. Send me all the baby dust!
