Belly bruise

I'm 33 weeks pregnant and have stupidly struck myself opening the cupboard 2 days in a row (must think I'm skinnier than I am)..It was at the beginning of the week and I've a bruise now. It's beside a big vein on my stomach but definelty bruised. The baby is still moving as usual and I've had no pain or bleeding. Should I get it checked or is this normal. To be honest it didn't really hurt bad when it was hit, I just rubbed it and carried on as normal.
