CM discussion

So after ovulation I never really dried up like usual, it was quite thick and creamy and there's was quite a bit of cm, my period is supposed to be here today According to glow and my cm has been a water like consistency since yesterday? So I have transitioned from thick and creamy to now watery? I had nausea yesterday morning and have had random spots of nausea today, I also had random cramps around 10 dpo and 11dpo but not extremely noticeable accompanied by back ache... I took a digital test 13dpo but came back negative and im scared to test again... any thoughts? Should I test again tomorrow or just leave it as I don't want to stress...
