Implantation bleeding help🧐

Ladies,

My period is supposed to start tomorrow according to glow. I woke up this morning with blood on tissue after urinating. So I'm thinking it's my period, but then later o checked my self it was brownish and pink. So then I thought maybe implantation bleeding, but I tested with Clearblue early detection yesterday a digital one and it came out negative🥺So I was thinking I wasn't. I've read mixed reviews about these things not really even that accurate. Not going to show pic, think it's TMI. I would be on cloud nine if it's a baby 🤰🏽 I have 5 and never worked this hard to get a baby . I'm 46 and been trying since Oct. as we age I guess it is harder. Feel like Sarah in the Bible..worship in the wait. And advice??

Baby dust to all🤰🏽
