Aunt Flo or Pregnant 🤔

September 9th hubby and I BD’d. My period was suppose to start on the 11th but it never showed. It’s been an entire week but still no sign of Aunt Flo. I tested 3 times but I got a bfn every time. Just yesterday I started getting these light cramps like Aunt Flo is coming. Today they’re a little mild but I can tolerate them. Whenever I get those cramps tho only last for 5 seconds or less. Along with those cramps my vaginal discharge is like a lotion discharge. Could I be pregnant or is Aunt Flo coming?
