Pulled abdominal muscles in pregnancy?

[pinkflamingo224]

I'm almost 16 weeks and for the last 24 hours I've noticed a sort of muscle strain achy pain all over abdominal when moving, it's not a sharp round ligament pain but more pulled muscle, (done nothing that would cause a pulled muscle) I've tried researching but can't find anyone who could relate to the same thing, I expect it's just due to expansion but I can't help have a little anxiety.

It's probably just because baby is growing and putting extra weight on your belly, I've had 4 and I remember getting very achy from about 16ish weeks when everything is starting to stretch a little
If you're worried though contact your midwife and see if she can see you, you could even have a little UTI brewing?
