TMI (no pic)

My husband and I had intercourse yesterday night, after we finished, before I even stood up I felt stuff flow out. Turned on the light and sure enough, a significant amount of watery fluid was all over, now I know semen will leak out, but this was like no other. The fluid was tinged pink. My AF is due anytime, but fast forward to 24 hours later (no intercourse since) and AF still hasn't showed. I did a q-tip test and it came back still pink tinged. Anyone ever had something similar happen? I've never had anything like this happen, and when my AF shows, she comes full force. I'm not a spotter.. we are TTC. Any thoughts, suggestions, advice is much appreciated. Thanks!
