hi fryertown
i've done it twice with MDI (multiple daily injections) - this usually consists of 2 basals & 3 boluses for me but like anticarb it turned into MULTIPLE multiple haha, because i too was popping insulin in lots - to correct high levels, to cover any snacks that weren't during normal mealtimes etc. i wasn't taught how to balance insulin with carbs, just to inject & eat a meal including starchy carbs & hope for the best! i kinda worked it out but can get it wrong frequently.
my last pregnancy was in 2009 and i was never told to keep sugars under 7.9 1 hour after. if my levels were double figs (actually over 9 i recall) would correct with insulin.
it's most important to be vigilant during the first 6 weeks, so 4 of those you may not even know you are pg...the organs develop early on, and they start to develop before you've even missed a period (so mid-cycle when you ovulate, from that point on you need to be on top of your levels...this was hell for me because we couldn't conceive so every month was 'trying' and 'waiting' in those 2 weeks, then period came so would let myself off the hook then would be v careful after next ovulation etc...)
i would love a pump and intend to enquire about it. my hbA1c was in the 6s before last time, and quickly dropped to 5s but this was aided by a whole lotta hypos. also, you need to take a higher dose of folic acid than non diabetics, before conception (5mg not the 400 something or other in normal folic acid) and this has to be prescribed by a doc - presumably you're on this if you're attending pre-conception clinic? from what i gather, if you become pregnant, the NICE guidelines advise that if you can't obtain good levels on MDI you should be offered a pump. this includes levels that are too low because your hypo awareness can drop significantly ( i had 1 unconscious hypo last pregnancy & 1 where i was unaware, and several near misses after that! not v nice and quite dangerous if you're on your own)
as you can lose hypo awareness in pregnancy, you need to become a frequent frequent tester, you become used to running lower so don't always notice when you're in the 2s!
well i seem to recall the increases in insulin came later, but having just found myself pregnant (v early 6 weeks ish, was a complete shock! thank god last A1c was 6.8 & levels have been relatively good) i am seeing my needs go up quite significantly, at least by a third. this is early but it is what it is! i am testing almost hourly.
good luck! armed with all the info i wouldn't necessarily wait for a pump, if you think you can keep on top with MDIs then go for it! i did it twice and looks like i'm about to do it all again (all being well...it's early days). i'm not sure i'd even take a pump if offered right now, what if i had teething troubles with it...not the best time to be experimenting!
hope this helps not puts you off! in the quest for that baby we can go thru anything! good luck!!!!!
