Probably going to Miscarry

Coryanne • Pregnant with baby #3!
I've been to two doctors appts with vaginal unltrasounds now and I am measuring around 5 weeks instead of 11. First ultrasound they didn't see anything, and at the second they could see a fetal pole (which may have been there all along). 
I have also been bleeding consistently (but not enough to fill a pad) for two days now. 
Has anyone else been through something similar?
