Pregnancy hopes

Hello all. First some background. I was diagnosed with type 1 at age 4. I struggled through the era of crummy glucometers and Nph insulin. I had insulin reactions as a kid, lots of PTSD, and puberty was just brutal. Fast forward to college and I started on insulin pump therapy and never looked back. I now have the latest Medtronic pump with CGM and my A1c sits in the high 5 range. I've never been over 6.8 in my adult life, but the CGM has helped me gain tighter control with fewer severe lows and less bouncing around to extreme highs. I have been married for just over 3 years and we are planning to start trying for pregancy in a couple of months. I'm 34 years old and I always had very irregular periods. Sometimes I would skip many months at a time. I even went a full year without a period in college. My doctor called it PCOS even though I didn't have any of the other features- I'm slim and athletic, no excessive hair growth or acne. My cycles did seem to improve as I hit my late 20s, but were never truly regular and predictable. Then I went on birth control. So for the last 6 years I haven't been able to see what my natural cycle is like. But I've always just assumed I would have fertility issues. Throw this in with the fears and apprehensions about being diabetic and pregnant, and I'm basically a mess. I'm a physician, armed with perhaps too much knowledge to let me sleep at night. The other terrible part of this story is my husband's mother actually told him to dump me shortly after we started dating because "diabetics have a hard time having babies...and they don't live long." So lots of pressure to prove everyone wrong. Thankfully my husband did his own research on the disease and decided to ignore his mother. But it's been a source of contention for me and her for years. I don't feel like I can ever forgive her for suggesting I'm not deserving of the same chance for a happy life and family as anyone else. I'm at that age where it feels like all my friends are seemlessly getting pregnant and having babies, and I'm just feeling nothing but dread and sadness. Anyone else in a similar boat?
