Any of you guys ever have an ectopic pregnancy?

I think I might have one and I want to know what experience you guys have had with them (obviously not good) and I apologize in advance for asking such a personal question I'm just really worried that that is what's going on with me... I haven't seen my gynecologist yet but I took a pregnancy test and it was faint positive and then took one the next day and it was negative . I've been having sharp dull cramps on and off on my right side, nausea no sign of AF , but little drops of blood.. etc ...and I'm just really worried ... does this sound like an early ectopic?
