Yesterday at 8/9dpo when I went to wipe there was light pink blood on the tissue and it had one small red mucus string in it. I wiped again and it was much less. There were never any clots. This lasted maybe an hour and got less over time. I've had nothing nothing since then. Just the same light cramps off and on,exhaustion,and nauseous. Af is not due for another 5 days. I've never bled mid cycle before. Could this be IB or?
