I second you are not alone. I am 5'4'' and although my pre PG size was a 14/16 my BMI was 32 according to the NHS.
At almost 38w I have gained exactly 2st. I have not tried to not gain weight but I certainly have been eating as healthy as I could (especially with the sickness and nausea I have felt all the way through).
Pre PG I was actively trying to lose weight, I did this by healthy eating (which I kinda mostly always did anyway as I'm not a sweet teeth person, I just ate the same size portions as my 6' DH) + counting calories by watching my portion sizes etc. and by exercise. I was doing 2 x 1hour burn it boot camps (yes those mega calorie burning sessions in the park led by mega fit guys that shout at you - I'd been doing it for several months and the guys knew me well which means I got pushed harder) I found that did wonders for my fitness levels. I also swam once a week and did gym once a week (mostly cross trainer followed by weight machines). And I did a salsacise class once a week. Due to this level of exercise the burn it instructors advised me to up my calories.
I didn't really lose a lot of weight (proabably only about a stone max over a few months - but goodness knows what my BMI was pre this exercise), however I felt fitter than I had done in years. I am so lucky I do not carry the extra weight on my tummy - as thats the bad area in terms of health. I do have an hour glass shape and the more I was exercising the more obvious my hourglass - cue the pencil dresses for me - I felt great!!
I actually had a BUPA full screen healthcheck sometime in the middle of all that, my results came back that I was as fit as a fiddle - I just had to lose weight.....(wish I had another muscle ratio thing done pre-PG that would have been interesting)
I know my DH and I were very blessed when it comes to TTC, we got BFP 10 weeks after my coil was removed.. 4.5 weeeks later and I felt sick as a dog. From week 6 to 16 I threw up between 6 and 8 times a day. I still take anti-emetics as I still throw up 2-3 times a week even when taking them (if I forget one - within 12 hours I am on the bathroom floor). Needless to say all exercise stopped as I felt so poop.
I gained 1.5st in the second trimester - I was so hungry and was chomping my way through half a greengrocers a day (a punnet of cherries and a punnet of strawberries and a carton of OJ were my snacks) Healthy choices I hear you say....but at my 28 week bloods I got a high random glucose and was given the GTT. I have borderline GD. (it was never mentioned by the MW that it was anything to do with my weight - simply as I had a random high) I am managing to control it by diet alone, but first thing the dietician told me was to stop the excessive natural sugars (she was happy I wasn't piling in the cakes etc) fruit and yogurt were the baddies now. I've started trying to walk more now too.
So since watching every single thing I put in my mouth for sugar levels I have only gained 1/2 st in whole of third trimester. It has been a pain and I never know what I fancy or what I want to eat but has meant I didn't need to take extra drugs for the GD.
I have never been weighed by the doctors/midwives. No one has mentioned my weight except 'it's a bit high' at my booking in appointment.
I have a very pronounced bump - in fact it looks like most of the 2st has been stuck on my front (the rest is in my ankles as water :)) I have had all the 'you sure it's not twins' and 'Your baby will be huge' comments. So I would say your chances of having a 'proper bump' are the same as anyone elses.
After the birth - I plan to start exercising again after I am feeling up to it. Starting with walking as many places as possile with teh sling or pushchair. My salsacise leader said I can go back after 3 months. I've heard of a yummy mummy pilates class in my area I plan to go to and the boys at burn it bootcamp has started a new mums specialist bootcamp :). I will not diet as I plan to BF but I want to get to the pre PG fitness level again. I actually may just give up the diets, just keep my food intake healthy - with an eye on portion sizes and just do that from now on. Maybe I'm not destined to be waiflike :)
Coicidently when I BF my DD (who is almost 12) the weight dropped off me and 3 months after the birth I was lighter than my pre - PG weight and a size 12.
If that happens again from BF - I will not complain, thats one of the added benefits for me.
Oh I just realised I wrote you an essay - sorry.
But basically:
- BMI is not the whole picture
- GD is not always related to weight - and if you get it you may be able to control it like me (there is loads of slim girls that go to the diabetes clinic too)
- you are doing great not gaining anything (I'm assuming MW is happy LO is growing fine) so really you already have a net loss
- If you BF you might find it easier to lose a bit more
- If you watch your food intake - remember you are feeding baby as well as you so make it as healthy as you can both now and after when you are BF - you just get into good habits
- Exercise again...get out an about with Baby in sling or pushchair and walk!
Good luck with the rest of your PG :)
