I don't think that's true... I don't think you can blame it on you still breastfeeding! There are plenty of people that do it (especially if they fall pregnant again early on after having their baby) and surely they don't all have a miscarriage!
I don't think it's right that she just said that to you! Way to make you feel bad!!
(no offence to your mum btw!! Just not very nice, but then we all say things sometimes that come across different to how we mean it, or things we maybe shouldn't say
)

If you are worried that that's why it happened and you're worried that it'll happen again then maybe up your calorie intake when you fall pregnant again, to be on the safe side.
I was trying to have dinner earlier, had some pizza but I was really struggling to actually eat it! Had some melon just now. Think I'm gonna have some of my popcorn now! Mental how much I eat and how many different things I have to buy just to be able to eat, cause if I'd have to eat the same things all the time I'd really struggle to eat!
It's bad enough as it is atm. I guess it's a good sign though, but once I hear that baby's heartbeat I would be happy for the symptoms to go!
As long as I can hear that heartbeat every so often at home! (got my doppler yesterday! Obviously not using it yet!!)
