Spotting 10 weeks??

Jackie

Has anyone had spotting in their 10th week? I just went to the bathroom and am having light brown/pink bleeding. I have not had any bleeding since week 6. I had an ultrasound yesterday morning and baby was dancing around with a 179 HB- I'm now extremely worried. My 3.5 year old did kick me in the belly yesterday afternoon, but I felt ok afterwards.. words of encouragement please!
