Fingers Crossed

My period is due in 4 days & I took a few pregnancy tests last week that were all negative. For the last few days I've had lots of strange cramping (some feel like menstrual cramps & others feel like a dull pain on my right side). I've been unusually gassy & burping a lot. My boobs haven't necessarily been sore but I'll get a weird sensation in them every now & again, if that makes sense. I've also been having super weird dreams (all of last week) & last night I had a dream I had twins lol. I honestly can't remember what early pregnancy symptoms I had when I was first pregnant with my daughter, which was 3 years ago. Do any of these sound like very early symptoms? I'm hoping so! I'll attach one of the tests I took last week. I can't tell if it's an indent line or what....
