Not necessarily because I only had brown spotting and was diagnosed with subscoroinic hematoma. I was very cautious because last year I had a miscarriage and any little blood to me is a sign of something.. good luck
During pregnancy it is normal to have some bleeding after sex. Also if you have an intra-uterine ultrasound. If it was dark spots, she is fine.
if I were you id have her call her doctor, they may want to check her out or they may just have her wait for her appointment since she isnt cramping and its so little.
Im 9 weeks and also had brown blood and I went to er and had subcronic hematoma
