Spotting?

Amanda • Miscarriage May 2018, Miscarriage March 2019. Pregnant with our Rainbow baby boy, due July 2020💕🌈

Anyone have any spotting going on in the 2nd trimester? 16+5 and had a smaller than pea size spot of blood today. I called my dr and the had me go to labor and delivery. Baby boys heartrate was strong at 168, they also did blood work to check antibodies of the previous rogam shot I had and see if I need another one. Still feel a little nervous. Has anyone else had this?
