Should i go to the er?

I have been having anal bleeding, a lot of it. My mom called the er and they said i may have a hemorrhoid, which i slikely because i was constipated for a while and a large-ish small red bump down on my anus. He said call tomorrow for an app. he said to watch for loight-headedness, vomiting, etc. I am also on my period... well, i ate dinner and i felt really light-headed, and began breathing heavy. We also found out since around noon today, our gas was leaking from our stove. Should i go to er or wait until he morning? he said call aat 7 a.m.
