IB on 4-5 dpo and again on 8? WARNING PIC INSIDE

[babydoll06]

I am so confused. On 4 dpo I had one wipe of watery red blood. The next time I used the restroom I had a small amount of a light tan-y brown discharge. The next day I had yellow cm with a blood streak in it. The next restroom trip had a small amount of watery pink discharge. That was it til today. Its been three days. Im 8 dpo. Tested negative this morning with frer and then a little while later wiped and had a darker brown creamy discharge. I checked my cervix to see what was going on and had a small amount of pink blood. I put a tampon in just in case and got this. More of the yellow cm with blood. We havent bd since 0 and I havent checked my cervix prior to thisso I shouldnt have caused it. My cycles are longer.. averaging 30 days. Im on cd 23 now. Whats going on?
