Blood scare

Savanna
Got my bfp on 10/25 then the following week on 10/31 I would be 5 weeks according to lmp and had pretty rough sex that day, layer into the evening I had bright red blood when I wiped and 2 Itty bitty clots, once more I went to the bathroom and there was very little blood when I wiped. After that there was no blood and none the next day. None of the time did I have bad cramps, super light cramps nothing like I have during a period. Called the doctor and she said since it stopped they don't need to see me until I bleed again or have bad cramps. So I still don't get to go to docs until 11/30. I'm so worried that I miscarried and it's been bothering me that I may not even be pregnant. A day or 2 ago I took another test to see if my lines got lighter but came up dark very quickly. Am I over reacting or is there a real chance I lost the baby?
