White flakes in urine? Pregnant?

I have taken the same steps toward my bfp.. but i found the guaifenesin pills in family dollar for $3.75.. 30 tablets 400 mg.. (I dont like the tase of cough syrup) and I also use instead soft cups.. I have not had any white flakes.. just lots of cm,cramping, sore bbs.. af due 9/15.. So really I guess I am no help to your question, just as excited as you.. hopes it works for you!!! good luck.. and post about the BFP in the morning!!! ------- first time using soft cups, i hope it works!!
