Faint positives, when should I test again?

Gracie
Hello all! 
As you can see, stick 1 is a bit hard to see the +. Stick 2 shows better than the first one but is still very faint. Stick 3 is the darkest of the 4, and the last one was accidentally soaked too long but as you can see, there's still a faint positive.  I have been getting these for the past couple days but none are as dark as these ones are today. The bottom two, 3 & 4 were taken today, the 3rd one being taken at 5/5:30 and the 4th one at 7:15ish. I have been having symptoms like crazy lately (my body is very sensitive. I had a miscarriage back in August so by guessing with these tests I'm just barely 4 weeks along. With my first pregnancy I got a bfp on the day of my missed period and then miscarried a week later. Trying to not get too hyped up but I'm in shock that these faint positives are actually there. 
Should I re test in the morning? Or should I wait until Tuesday, the day AF is expected? Should I even consider these positives yet? Let me know what you think/what you would do, please and thank you, baby dust to all!
