Expert answer:
In relation to your bleeding: an abortion would only be possible if you were already pregnant for more time, if you became pregnant this month and already aborted would hardly have a large bleeding or with severe pain, the most likely is a bleeding from the morning after pill or your menstruation itself. Diarrhea may have been mere coincidence and means a food poisoning or intestinal infection. I do not think you need to do anything now that you're better.
