I began to notice some type of bites appearing on my body about 3 weeks ago.I never thought anything of it just thought they were msqueto bites because they itched and were red,it started just a few on my toes then my feet and now they have also got onto my legs, arms, upper back, sides,even my fingers have bites on them.I have a dog and an older matress, I thought maybe they could be a reason too? Please help, it feels like they won't quit itching. I have a three month old and I'm scared whatever it is that is biting me could bite her too, neither her or her dad have them just me.

Possibly fleas or bedbugs? You could call an exterminator in to determine what it is.

I assume you didn't drag in any used furiture recently... or have stayed at other peoples houses or hotels recently. That would make fleas a more likely possibility... but bedbugs are still possible.

Could be fleas, bedbugs, or scabies. Also could be a rash from an allergic reaction. Also could be something like chicken pox or shingles. Given you are pregnant (I assume from where you posted the question?) you should not ignore it - go to the doctor immediately.
