TTC // Need Opinions

I took a pregnancy test yesterday approx 5PM and it was a faint positive. I took one around 1am when I got home from work and it was negative. I took one approximately 3:30PM today and it was negative. The two negatives were blue dye (if that even means anything 🤷🏽‍♀️) while the faint positive was pink dye...

My honeymoon was approx. 4Weeks ago and my hcp told me that approx 6weeks ago when I got my nexplanon removed it was possible for me to get pregnant because I had sex multiple times in the previous days. I have been exhibiting symptoms such as peeing more frequently and sore breasts! Just not sure if it’s related to pregnancy

Should I get a blood test or wait a week and retest???
