Pregnancy after weight loss - scary!

Sorry if this isn’t the right sub for this but just looking for some advice.

So back in 2024 I lost 47kg and maintained that throughout 2025. Due to an injury I’ve recently put on about 12kg but all in all I’m still massively net negative.

I unexpectedly got pregnant in February and unfortunately had a miscarriage however it’s changed mine and my partners minds on children and as such we’re going to actively start trying for a baby.

I am PETRIFIED of gaining all that weight back throughout pregnancy, and I know there’s other things to worry about, but it’s something weighing massively on my brain.

Has anyone experienced this? How did you manage it?
