In pregnancy, only metformin and insulin are safe for the baby. I don't know where u are based, but pump in pregnancy is only for type 1 DM in Ireland.
Unfortunately, none of the GLP-1 agonists is known to be safe in pregnancy. In fact, you are advised not to conceive while on these medications.
I have had two babies with gestational diabetes at early gestation (24 weeks and 18wks - on both occasions was on insulin only, offered metformin in my 2nd pregnancy, and couldn't tolerate s/es.
I am currently been managed as a type 2 although maybe a LADA, on Victosa (similar to ozempic but daily dosing).
