Advice.. 2 weeks late, symptoms are:

No period. I had only 1 day of spotting and it was the brownish blood for less than a day. I'm really bad at this app and still new so I need to track better. About a week and a half ago to 2 weeks I had a couple nights where I was super hot all the time, mini headaches and super moody. Cramps kinda period like. Insomnia but super tired during the day. Zero energy. The last 2 weeks have been like this off and on. My cm the last week has been alot . First eggwhite and then watery and then last couple days milky white. Still have the cramps and lower groin spasms. Super irritated and moody. I feel bad for people around me. Made an appt for Tuesday for test. In the past home tests said negative and I had a miscarriage about a year ago. Freaking out, any thoughts or advice? Thankyou
