i agree with seeing a doctor. sorry to hear you've been feeling so unwell

if you do end up with GD again then i'm pretty sure it takes a bit longer for the condition to develop (i was told that if it exists so early in the PG then it was probably type 2 rather than being a PG thing ). definitely get your BP checked though & if you still have a monitor to test your BSL you could try taking them after eating just to see what's happening?

hopefully the GP will order a range of BT so you can see where everything is at
