Second trimester

Pantera

I’m in my second trimester and I went to the doctor Wednesday and the nurse stick her finger inside of me to check that was my first check up for that and it’s my second baby I’m not cramping and I pee when I have to pee so when I had to pee I wipe the first time and it wasn’t really nothing there then I wipe again and saw that and the doctor said I will be spotting a little Wednesday she told me that should I be worry or it’s normal? Idk why it’s not letting me post the pictures but it’s light pink blood
