Need advice!

Emily

I have had a cold all week and then Wednesday night had some pink spotting & have sense. I went in yesterday just to make sure all was ok. They did a quick ultrasound and said everything looked good. The heartbeat was at 122, which made me nervous because it had been at 160 the other times but they said that’s normal. Was hoping it would ease my mind but I’m still spotting today so it makes me worry. Any words of advice besides everything will be ok stop freaking out? I am 16 weeks and also had spotting at 12.
