10 weeks pregnant strange sensations

Sa

Hi ladies, have any of you experienced a strange pulling/tugging vertical sensation from about where your uterus is to your vagina? It's very off and on and definitely not persistent or severe but I have been noticing it yesterday and today and wondering if this is a common sensation when 10 weeks pregnant? I am currently 10 weeks and 3 days. We saw a healthy little baby with heart beat at 8 weeks and 4 days so I am trying my best not to worry.
