Spotting

Has anyone had brownish/pink spotting during pregnancy!? About a month ago I had it and everything looked fine when I checked in with my doctor. A week ago it started and I called the Dr who had me go to the hospital since it was the holiday weekend. Again everything was ok and they didn’t give me any restrictions. Tonight it started again!!! Ugh it’s so frustrating. Anyone else experience this? Any suggestions? I still feel baby moving but I’ll probably call the Dr tomorrow
