Pregnant or not???

Hi ladies. I'm looking for support during this waiting period. We have been trying to conceive for 2yrs AF was due two days ago I've been having that heavy feeling in my lower vaginal area as if AF is coming and a drop of blood after intercourse a few days ago, but when I go to the restroom nothing is there. I haven't tested because of fear of getting a BFN has anyone else experienced this? Should I test now or wait? HELP!!!
