spotting after sex

at 6dpo i had a small amount of brown in my CM, along with sharp cramps (different than my AF), Lots of gas, mostly burping allllll day, and sensitive nipples (which isn’t normal for me). I was feeling like this was my month, but then after sex today I had a bit of spotting once we pulled it out. This was super discouraging because it’s a regular thing for me to bleed after sex a few days before AF is due, which is 4 days from now... am i out? or is bleeding after sex also a sign of pregnancy?
