Hello. : Hello. Although this doesn't state it; I am assuming that your boyfriend was having very vigorous sexual intercourse with you. First off, i recommend that you slow down on the sex; both because you may have had an injury and secondly because of your age. The thrusting of his penis may well have been hitting against tissue or organs. I recommend that you give him direct feed back about this. Sometimes young guys think that harder is better, but that is often not the case. It sounds like your pain is abating. Like any bruise, it may take awhile for the pain to resolve completely. If you develop severe abdominal pain, especially if tender to the touch or significant vaginal bleeding or fever from this episode, those would be reasons to get urgent medical care i really hope that you all were using birth control. Take good care of your body. It is the only one you will get in this life time. Be gentle with yourself and tell your boyfriend to be gentle as well.
