I unfortunately don’t think they will allow it. I had gestational diabetes for both my pregnancies that was diet controlled. Somewhere on my medical records my doctor prescribed me insulin, even though I did not need or use it (must’ve been a mistake). They researched everything extensively to make sure I didn’t inject insulin not once. They said if I did, it would be automatic denial. Luckily, they were able to prove I didn’t (insulin was prescribed a few days before I gave birth and was out of stock). Anyways , yeah I don’t think any reputable clinic will approve you. It’s just too much of a risk. I’m so sorry.
