Spotting

I am 16 weeks as of Friday. That morning after peeong I wiped and light pink was on my TP followed by pain. I called my OB they said nothing to worry about that it's normal and to stay hydrated. I have since felt way better other than gas. Today I had a bowel movement and wiped red but no cramping. Not a lot either time but it still makes my heart skip since this is rainbow baby. Anyone else experience this that can still my heart?
