Guess I should test again!!!

So I’ve taken 3 tests and all were negative before my missed period. But 4 days before my period I had some blood. It was a little red at first then mostly brown spotting that appears a bit slimy or mixed with mucus here and there over a couple days. I’ve also had some cramping. I’ve had 2 other pregnancies and never had bleeding or really any cramping prior to my missed period. Only symptom was a missed and constipation. Tomorrow is my projected period date. I am currently on vacation and don’t get back until Wednesday. So I will test then! I honestly thought maybe I had my period early. I’m always very regular and usually have my period within a couple days of what Glow says. Fingers crossed and praying for God’s will be done! My kids will be excited if I am pregnant. Especially my oldest who is 5 and has been asking for a sister for over a year!!
