Miscarrying

Lee • Mommy to 3 year old girl! Baby #2 joining us March 2016!!!
I've been spotting for 2 days. Yesterday I had an u/s. The baby's heart rate was only 98 (it should have been over 100) and the baby only measured 6w1d. (That would have ment I got a positive preg test at 2w5d). So I think the baby is measuring smaller than it should. I haven't had any pregnancy symptoms. I feel like all signs are pointing to the baby not making it. I'm heartbroken.
