Pregnancy swollen tummy

[Luna87]

Hey all, I'm currently 8/9 weeks pregnant with my 3 child. I don't know whether I'm being over anxious but I'm worried something is wrong, I've been suffering from an extremely swollen stomach accompanied by regular bouts of light headed dizziness.
I was only 4 weeks gone when both my sister and mum asked me if I was pregnant because my stomach had expanded so much. I now look like i'm well into my 2nd trimester, I never had this with my other 2 pregnancies. Could this be a sign that something is wrong? I've not stopped working out either so it's not just weight gain.

Hey!
Not sure it’s anything to worry about as such because apparently extreme bloating is normal? That’s what I was told.
I’ve been suffering really really badly too! I looks well into my second trimester with my tummy! It’s horrible and uncomfortable so I do sympathise with you! X

I've been super bloated since the moment I found out I was pregnant. This is my first pregnancy so nothing to compare it to. My stomach swells up like a balloon, especially at night. I've read it's hormones slowing down the digestive system and causing bloating, which my midwife agreed is likely the cause. I'm not worried (just haven't been able to fit into my jeans for a while and I'm only just 12 weeks!)
