Spotting

So last night I went to use the bathroom and I saw pink blood on the toilet paper when I wiped then in the toilet a drop of pink blood ! It went away but I’m still nervous because I had a miscarriage about 7 months ago I hope it doesn’t happen again , I had no cramping so it caught me by surprise, any tips on what to do to avoid any more surprise spotting ? Is it normal ? My nurse said since my history of miscarriage it’s not normal :/ just to look out for any more blood:/ helpppp
