Are these Flea bite or Bed Bug Bites?

I have a picture here :

I felt the bite last night, and it was pretty itchy woke up this morning with 5 bites, in the shape of a 5 on a dice, pretty funny.

They don’t itch – but are red, swollen and pretty gross.
I have a 1 year old daughter who co-sleeps, she didn’t get bitten but if it’s bed bugs then we got a lot of work to do to get rid of them.
I also recently got a mattress from a friends house and she owns 4 cats – so could be that?

Sorry photo is dark.
Any ideas?
