Higher BMIs and pregnancy

I'm not sure if this is the right place, but I couldn't find much information online and figured people's personal experiences might help me.
I had my first LO last year. My BMI was around 46 when I got pregnant and 48 by the time I had him. There was no real problems with me getting pregnant or throughout my pregnancy. My blood pressure and body was fine, I didn't get gestational diabetes to most the medical professionals surprise and had a gorgeous 9lb healthy baby.
But, I want to be healthier for my baby, I want a 2nd LO, I don't want the pressure and worry of my weight, I don't want people to look down on me for having a 2nd baby while i am still fat.
I have now lost 2 and a half stone since new year and still going strong.
But, health professionals obviously all say a bmi of 18 to 25 is healthiest. But what is the maximum bmi i can have without needing all the extra care and scans.
Has anyone had a bmi of 25 to 30? Or 30 to 35? Or more and still needed the extra care because of your weight? I wanted to try for baby number 2 in September, but I really don't think my bmi will be 25 or below by then. Probably more around the 31 mark.
How will this impact on mine and my babies health?
Any advice or experiences I would be extremely grateful.

My BMI was around 29 when they first checked me and they didn't flag me as higher risk because of it. I am in the higher risk group because of age (I'm 40), and getting extra scans as a result of that, but they didn't put me down as high risk of gestational diabetes. 30 is the cutoff point between overweight and obese, so I think that is probably the 'magic number' that you want to be below.

Well done on your weight loss, by the way. It's hard work, I know!

sophherts · 16/04/2018 16:27

Mine was 30 at booking in so I've got to have the gestational diabetes test but that's the only additional thing!

ClareB83 · 16/04/2018 16:32

Yes 30-35 you still get the GTT test but not much else.

35-40 they start trying to send you to healthy eating classes, prescribing aspirin etc

mommybear1 · 16/04/2018 16:37

My BMI was around 32 and rose to 33 they didn't flag me as higher risk because of it. I was however in the higher risk group because of age (I was 38 when I fell pregnant/ 39 when pfb arrived) I think it depends on your area in terms of what they class and treat as high risk due to resources.

Congratulations on your weight loss, keep going!

Anything below 35 is generally considered fairly low risk. I had a bmi of 30 when I had my 2nd. I’m healthy and was considered low risk. I had a home birth (also did for my first). I was offered the GTT but declined and midwives were happy with that. I think over 35 you’d get a bit more monitoring especially if you have any complications and definitely over 40. I wouldn’t stress about it though. You’ve done a great job losing weight so far and obviously have a history of relatively healthy pregnancies.

MsHopey · 16/04/2018 18:19

Thanks for the advice everyone.
I've got my bmi doen from 48 to 42.
Definitely doing to get it below 35 before we start trying regardless of how long it takes. But I didn't want to wait years because I didn't want a massive gap between the 2. I am quite young and healthy in most other aspects, it's just the weight that is a major problem.

I'm 35 BMI and in a high risk catogery so have to see consultant and take asprin.

Buxbaum · 16/04/2018 23:39

It depends on your trust.

MrsDx · 17/04/2018 06:41

I’m 28 and they haven’t mentioned it yet.. I’m always waiting for the ‘overweight’ comments from mw 😢.

DryHeave · 17/04/2018 06:46

I was 29.5 and had several comments and a phone call about attending a session on diet.

pullthecracker · 17/04/2018 06:49

Anything over 30 we class as high risk, a higher dose of folic acid is needed, so see the go or midwife as soon as you know that you are pregnant. We refer to the consultant, but below 35 you may only need one appointment and they may or may not do extra scans for growth as fundal height measurement isn’t always as accurate as it could be with a higher bmi.
As pps have said, a gtt is advised with bmi over 30 also. 35 and above is classed as more high risk and growth scans will be done with more careful monitoring, and aspirin from 12 weeks.

Kellie137 · 17/04/2018 06:53

My bmi was 39/40. My Midwife was fine and I was told I’d have extra scans because of his but this and was consultant led but nothing was ever mentioned about my weight really. I ate healthy throughout the pregnancy and everything was fine. If you have a bmi of 45 or over my consultant said an anethetist speaks to you and recommends you have an epidural in labour (due to Higher risks of instrumental delivery)

muffyduffster · 17/04/2018 07:11

Yep my trust has an over 30 BMI risk box and then goes up again to the next risk level at 35. Mine is late 20s I think as thought I might make the first one this time and didn't!

SharedLife · 17/04/2018 08:19

Go to the GP for the higher dose of folic as soon as you are TTC, 3 months in advance if possible. The neural tube is formed in the first 28 days from conception so the right dose of folic acid is vital as early as possible.

cazinge · 17/04/2018 09:20

Mine was 33 at booking in so they put me on a prescribed dose of folic acid (500mg I think) then I had the GTT test @ 28w which came back negative. My bump is measuring big so I did have a growth scan @ 31w but baby is on the 50th 95centile.

Am now 35+4 & touch wood no issues, am under midwife still, never even seen a consultant, BP normal, etc.

cazinge · 17/04/2018 09:20

50th centile- don't know where the random 95 came from!!!

Lndnmummy · 17/04/2018 09:40

My bmi was 28 at booking and my midwife didn’t bat an eyelid. My age was more of a concern (39). No extra scans only gtt tests.

I have managed my weight gain carefully this time and at 28 weeks have put on less than a stone. With my first I had a bmi of 23 at booking but put on 4st during pregnancy and it was just way too much.

MsHopey · 17/04/2018 17:20

Thanks everyone for the advice.
I am trying very hard and I am losing the weight.
I've dropped 2 dress sizes.
I have my sister's wedding at the end of June, I'm trying to lose weight for that and also wont be trying for a baby before then because I already have my dress and don't really want to steal her thunder. Then I'll give myself a few more months to shift a bit more weight.
I should be able to get to a size 16 and a bmi of around 33 by September.
