Weird situation

Briana • I`m the mom to a sweet little one already, and I am expecting a new little love in August. So blessed. 1 Samuel 1:27
I'm about 5-7 days late. Yesterday I had some very light pink discharge. To double check it wasn't my period I wiped again. Nothing. So I figured, ok just some discharge. (Pink and mucus-like.) Ive urinated more than usual lately and I have a (tmi) bowel Problem to where I can't poop but lately I've been really gassy and pooping much more. My breasts aren't sore. Here's the catch. I've taken 4 pregnancy tests in the last two weeks. ALL NEGATIVE. I'm hoping for a pregnancy but with the negative tests I'm not sure. When I had my first daughter I was around 5 weeks when I found out I was pregnant. Should I wait another week?
