Pregnancy advice. Someone please show concern, read, and respond. Should I worry or not?

I don't think you are pregnant, and I think a test kit would tell you. BCP do not work when you take penicillian anyway. you would need a back up birth control. Are you wanting to be pregnant? I don't want to be rude, but as much trouble as you are having with this, I don't think you would be able to care for a baby, as you don't sound that mature.
