Ok, I'm 33, and have two sons. my cycle is super unpredictable. My SO and I had sex yesterday morning. After the sex, I went to the bathroom. The tp was pink, so I assumed AF had just made her debut so I popped in a tampon, a couple hours later, I went to the restroom, and there was BARELY anything on it (any other time, it'd be completely saturated) and NOT a drop since. This morning I wake up thinking AF just tricked me and I'd prolly wake up covered in blood. Not close. Still no sign of blood but I woke up with the absolute worst type of indigestion there is (it's like farting out of your mouth GROSS!! Tastes and smells like a fart). I've had this condition only 3 times in my life prior to this morning. (When I was pregnant with each of my sons and right before I had my gallbladder removed)
