Pregnancy Help (TMI)

Okay ladies so me and my fiance have been trying to have a baby for a while know an we had no luck so we both started wanting to just give up because we thought neither one of us could have kids but today i started feeling like i was getting cramps like if i was to start my period the app says i dont get it tell the 3rd but sometimes its off a couple of days well i went to the restroom an i wasnt bleeding like a normal period in the begging. It was more like im going to try my best to describe it cause i dont really know how but it was like clear mucous or discharge mixed with blood should i be worried or what this has never happen to me an im beyond scared we bought a pregnancy test but i havnt tooken it yet but if anyone has any info about this it would be very helpful thank you girls so much.
