Spotting

Yadira • 26 years young.. In love with my best friend.... Pregnant with our First Baby
I'm 7w5d I started spotting today after work around 7 pm.. No cramps just spotting but I did cramp earlier at work. Should I go to the er or just wait for it to stop. It's been two hours or a lik more. It's my first baby... I don't know what to do
