A Little Over A Week Ago, My Boyfriend And I

A little over a week ago, my boyfriend and I had sex and the condom broke. I felt cum running out of me when he pulled out and it was a lot. He said he came deep inside of me only to find out the condom had broken so he pulled out. I was fine for a day and the next day I noticed very light brownish-pinkish bleeding in my underwear. An hour or two later, I started light bleeding. This lasted for about 4 days with no lining or symptoms like I usually have. It was very bright red, almost pink. My period is due some time next week. I'm worried that I could be pregnant, but even more worried that it may be bigger health issues. I am still in the process of searching for another Ob/Gyn at the moment so seeing one isn't possible yet. Any advice or tips would be much appreciated.
