Insecure about weight gain first trimester

I know it’s really selfish of me so be to shallow and I feel guilty for feeling this way but I’m wondering whether this rapid weight gain is normal . 10 weeks ago I was a size 6 with 30B boob (I’m 10 weeks pregnant). And now the clothes I had that I once deemed to be ‘baggy and loose’ and now getting tight. I put a top on yesterday that’s meant to be roomy and it’s tight!

I know my body is doing the most amazing thing to grow a human but I’m a little concerned about the weight gain. I feel so shallow but I’m really terrified that I’m going to ‘let myself go’ and not look glamorous anymore. Haha! Just saying that sounds so selfish and I know deep down it’s for a great cause.

but seriously… my mum gave her comfy joggers yesterday because I was having bloating cramps so I changed out of my work trousers… and her trousers NEARLY fit me. And she’s a size 14!! How can I go from being a size 6 to a size 12???

I feel like I do have a bump which makes it feel better but apparently it’s just bloating at this stage. How fat am I going to get? It’s weird because at my antenatal appointment 10 days ago I weighed 53kg which at most might be a couple kg more than pre pregnancy. So how can I look so big if I haven’t physically put on that much weight?

My partner think my boobs have grown so much things are looking tighter, but I’m not sure. It feels like everything.

When the bump ‘pops’ will I feel better??

Honestly in first trimester bloat has a lot to answer for!! I wasn't thin pre pregnancy but I had lost some weight and have found it very difficult not being able to fit into my favourite clothes again. You can feel upset at changes as well as being happy for being pregnant, the 2 aren't mutually exclusive.

Boobs will also most likely be growing - they tend to start growing pretty early on! The other thing is, you're meant to put on weight in pregnancy. So it might help you to find a way to come to terms with that, because it's almost certain you will gain a fair amount. It's nothing to worry about and you can lose it again once your little bub is born 😊

I’m afraid it’s an inevitability of pregnancy that you will get bigger - you need to work out how to accept it, as you will probably go back to ‘normal’ afterwards.

All your clothes feeling tight is unpleasant though. I also found I got a bit sensitive to anything being constricting - which is why suddenly even something a few sizes larger than usual might not feel quite right either.

I do think you can feel a bit better about it when you ‘pop’ as at least then you are noticeably pregnant…!I think buying some clothes that fit and ignoring the number on them is probably the best thing to do though.

I know how this feels! The bloat during the first tri is BAD, and you'll be swollen with water retention and all the extra blood too.

I will say I'm 23 weeks and the bloat is a lot less than it was. Flowy dresses, leggings and big t-shirts have saved my self esteem many times, even if they're a size or 2 bigger than what I usually wear. You'll probably get hungrier during the second tri, try and embrace that too. Our bodies are incredible, but they're also going through so much stress. I'll worry about the weight gain after baby arrives, and even then it'll be far from my top priority.

Go and buy yourself some maternity leggings!!

I am also a size 6, I feel like it seemed like I got bigger faster because there was barely anything of me to as soon as baby started growing there’s nowhere for it to hide, so I seemed bigger sooner (unlike women who are taller with wider hips where they can keep things hidden for much longer!) I was wearing size 14 pants at the end. I’ve had 3 babies and my body has always slowly naturally gone back to the size I was before.

12 weeks and 6 days and I feel the exact same. The pregnancy bloat has stressed me out so much! I’m pretty sure I don’t have an actual bump yet because my stomach is normal flatness when I wake up, but by the time I go to bed the bloat is real!

I feel bad being concerned about it, but I’m still trying to hide the pregnancy and am annoyed my sudden switch to leggings and big shirts is a dead giveaway even without an actual bump. I was a size 8 before and lived in high waisted jeans and cropped T-shirts and vests but all my jeans are so uncomfortable now.

I was weighed recently and had gone from 52kg pre-pregs to 56kg. I really had to remind myself this was ok and good for the baby that I’ve been eating better. When I’ve got a clearer bump and have told people I’m hoping to feel better, hope you do too 🙏

This! I was about 51-52 kg before I was pregnant, then 53 at my antenatal check up and I went to the gym this morning and I’m 54 now! But you’re right- it’s super healthy for the baby and I’m not actually eating anything inherently bad. Mainly fruit / meat and maybe slightly more bread to deal with the nausea but it’s not like I’m eating loads of crisps and sweets and chocolate. Ironically I ate more of the bad stuff when I was tiny!

It can be really difficult getting used to your body changing, and totally not shallow. I was about the same weight as you pre-pregnancy, about 50-52kg, and I think being smaller the bloat does feel more noticeable (though not a single person did actually seem to notice!).

It definitely gets easier when you get a proper bump. I'm approaching 37 weeks now, and I'm actually ok with my body for the first time in years since the bump takes all the focus anyway 😂.
