Doubt it. From the information I am getting this was your first time. It is normal because your "area" is not used to that and it can cause bleeding from trauma and being stretched. Just try to relax because I really don't think you are pregnant. If you are thinking about having sex though you may want to get on some birth control and also always use condoms esp because neither one of them are 100% baby proof as well as birth control does not help prevent STD's. Stay safe and good luck but relax.
If you had protected sex, the chance of pregnancy is slim to none. Try not to worry about it as it can delay your period and add more stress. If you're going to stay sexually active, make sure you always use protection, and I would suggest birth control as well.
