Hi. Im A 28 Yr Old Female, 146lbs. I Have

Hi. Im a 28 yr old female, 146lbs. I have been having bruised feeling for about alittle over a month that started in my right hip and now it seems to have spread to the rip of my pelvic bone. There is no discoloration. I didnt not injure/have any trauma to that area.i stopped sleeping on that side thinking maybe that was the case, did not help. I have the most pain when lifting that leg up when getting/on/off my bike. There is discomfort when pressure is placed on area. Occassional rectal bleeding ( not dark red, pink on tiolet paper so not a large amount of blood/same amount from vaginal area randomly in the past 2 days - 2 weeks out from next cycle). took a dose of vicodin on the 16th (i used when i got my wisdom teeth extracted) & Spotting seemed to start the next morning after the tablet dose. Unsure if related to medication or tied to bruising somehow. In the past month i have been on 600mg IB and 875mg Amoxi for my widsom teeth, and the occassional flonase /claratin dose for allergies.
Not sure if i pulled a muscle but since the lain has moved up and is still going on a month later im getting alittle worried.
