What do you think?

Had unprotected sex on the 15th. He pulled out. Period was supposed to come yesterday woke up with wet light brown discharge on panties. I wiped twice before peeing and there was still brown I put on a pad & hours later I use the bathroom again and the paper and pad were clean. Woke up this morning without the brown discharge or period. My cramps come and go but are not bad. I took a test but it was negative.
