So friday i had alot of cm mixed with a drop of blood..not even a drop and the micus was clear..i had light cramping and some back pain as well.i tested Saturday and got what look like a vvfl, like hardly noticable..sunday i tested again and got the same thing, a vvfl but a negative digital clear blue..i read that digitals need more HCG ..today i tested and it looked negative..i put in that i was pregnant and it said that i would only be 3 weeks and five days and that was Saturday so today i would be 4 weeks...idk if im testing too early or what but im sure i wasn't seeing things Saturday..my period is due in 5 days btw..heres Saturdays picture..i also miscarried last month on the 2nd
