Any experiences??

Last night me and DH had sex and after I realized I had started bleeding. I figured I started a day early and put a tampon in and went to bed.

Usually if I start bleeding especially near AF it doesn't stop but goes into full swing immediately. I woke up this morning and there was NOTHING on the tampon and I haven't bled or had spotting at all today and im due for it anytime.

Has anyone had this? Did you just end up starting late or actually been pregnant?
