Type 1 diabetics ONLY BC question

Hey guys I’ve been type 1 since I was 4 I’m 20 now and I am 3 months postpartum. I had an IUD placed at 6w pp and honestly my blood sugars have been HORRIBLE since. I’m talking about constantly being in the 250-350s and it’s been like this for WEEKS. I’m back up to my mid pregnancy bolus carb ratio, correction dose and taking 24 units of basal rate 😭 I constantly feel worn down and sick and so thirsty and cranky. I’m so tired of my

Blood sugars being so fucking high I’m about to loose my shit.

I have mirena to be exact has anyone else had issues while on it? We use condoms while I’m on the mirena anyways honestly at this point I’m considering switching to a copper IUD or the mini pill cause we can continue using condoms...

I need help/ advice anything 😭 could this just be from postpartum? I was pumping for 11.5w I’m 15w pp now I just I’m so flustered
