I'm 32 and I'm pregant with my 3rd. I have a girl and a boy both under 3. I'm 5weeks along and this time I'm having no morning sickness but I am having body pains I normally don't get til well into my 2nd tri with my other 2 pregnancies. !st off I'm having on and off cramps and slight lower back pains. There is no blood so I'm not worried. I'm peeing more often then I normally do in my 1st trimester. Also I gained 3pds. in just being 5wks. pregnant. Could I be carrying twins???
