Ovulation ?

Cynthia • 20, engaged and ttc.
Okay ladies. I starred miscarry ing Saturday on the 8th. From what I've read I should start that day as my first cycle day . Well I'm supposed to stay my fertile week in 2 days according to glow. But for the last 2 days ice had an increase in thick white cervical mucus. Like when we have sex it's on him and any other time it's in my panties . I usually get this around my fertile time . Idk if it's the egg white mucus everyone is always talking about. But my quotation is should it be starting this early if my week doesn't even start for 2 more days ? Idk if having this miscarriage changed my cycle or not but I'm just curious as to what you women think ? I usually have a normal 28 to 29 day cycle. So today would be my 10th cycle day. Also Friday I wad having these cramps in my hips that I have never experienced before. Both sides. Didn't lay long. Just a few seconds reach time it started . Don't know if that's even relevant but I figured I would throw that in there. Thanks in advance for any input :)
