20 weeks - bruised/tender abdomen?

[miamix]

I'm almost 20 weeks and the last few days I have noticed that the right side of my bump feels tender to touch, as though it is bruised. I know that this is the baby's favourite side and I'm not feeling her move as frequently as I was (but this might be because I'm not paying attention - it is still early to be feeling much). I definitely haven't bruised myself on impact but I have been straining a bit recently doing some painting and jobs around the house so could it be muscle soreness?

Anybody else have this?

Thanks x

I've had this at the top of my bump (am 24 weeks) - did wonder if it was a hernia, but after a day or two the pain disappeared, so I think it was just a pulled muscle. Obviously overdoing things a bit. Keep trying to use my tummy muscles, forget they don't quite work the way they used to!!

Thanks goodlife, this definitely seems likely for me as well.
