Anyone experience this ?

Brittany • Christian Mother , & wife ,baby number two Due march 27th??
So according to the many pregnancy test I've taken they've been faintly positive . Today I was so sure AF was coming because of cramps that lasted about 20 mins , eventually they went away I ran to the bath room only to find a ton of cm . I go to the doctor thursday so I'll find out weather or not I'm really pregnant or not then . Anyone else go through this ??
