I need help

M

May 28th i miscarried at about 6 1/2 weeks. I only bled for 7 days and was done my hormone levels went back down to 0. I still have not gotten a period BUT i did notice i was having cm like eggwhites. But still no period. When is the BEST time to try to take a pregnancy test. I dont want to wait until a "missed period" but i dont want to wait too long when i could already be pregnant, if that makes any sense. . .
