6 week and spotting

Crystal
Hi ladies... first time mommy here! Hubby and I are excited and can't wait to meet our little sweet pea! I am 6 weeks and 1 day according to my primary care doctor (first ultrasound and prenatal visit with my OB is in two weeks).
I wiped this morning and had light pink spotting and a little on my underwear as well. Should I be concerned? I've been experiencing little pulls and cramping since we found out, but I figured that was normal growing pains. Any advice is much appreciated from this new and concerned mama to be. Thank you!
