I’m really anxious (((tmi)))

Hello girls, I really hope someone can give me some advice.

My last period came a couple of days early and only lasted half a day it was medium flow and was dark and bright red, so I thought it couldn’t be implantation.

I still did a test about a week and few days later and got a BFN. So I counted it as my period.

Now, I’m on CD22 & the last week I’ve had mood swings, emotional. Light cramping in uterus started yesterday on and off, tired.

Last night and just now I’ve just got all this thick cm, there is loads.

It doesn’t smell or I haven’t got any other symptoms down there..

Has anyone else had this?? I’m so worried.
