You are 16 weeks pregnant and spotting just a litte but you got cramps and pain your lower back should i be worried?

Hi! When I was 16 weeks pregnant with my daughter, I had mild spotting and cramping that lasted about 10 hours. I went to the hospital and after an emergency ultrasound and blood work, they told me everything was fine. Apparently it's normal to have mild spotting & mild cramps from time to time during a pregnancy. I hope that answers your question and wish you the best of luck with the rest of your pregnancy!!!
