Sporadic pains when bending over/down?

Annie
I'm 4 weeks 5 days & everytime I bend down to pick something up, I get these sporadic pains in my pelvic area. Does anyone else experience this? My first ultrasound isn't until 12/08/16, so I'm just hoping this is normal & maybe instead of bending over to pick something up, I'll need to squat down instead.
