My bloods were all over the place when I was pregnant (t1) so bad that I had to spend around 5 months in the hospital.
As for the cravings, it was only cheese with me so it didnt effect my sugars too much.
Even to this day (9yrs later) I could eat cheese all day and still want more lol.
Sorry to hear about your miscarriage but as they say, 'everything happens for a reason', I miscarried 5months before I fell pregnant with my little girl and I changed soooo much in that time.
Good luck for when you feel the time is right.
