I ended my period the last day of April and I had sex for the first time 3 days ago. Sunday I noticed as I went to the bathroom light spotting, Monday it was not all the time and today when I woke up there was a lot of blood, we did not use a condom. Is this normal? Help

No, it's not normal, not heavy bleeding.

What does a "lot of blood" mean?

You are not using protection so I am guessing you are trying to get pregnant - ?
