Any signs of pregnancy before your period?

So I've read that some women don't have enough HCG levels before their period to register on a pregnancy test. I already have two children. I didn't test early with them because I never showed any signs before my missed period. So I don't know for sure if I am one of those women whose HCG levels are super low before their missed period. I have taken a few tests 3 & 4 days before my predicted period. They have all been negative. Has anyone ever had this happen?

How early did y’all start showing signs of pregnancy, like nausea, mood swings, etc. Like how long before it showed positive on a test?

For all the moms out there, what were your guys first signs of pregnancy before you tested? I could possibly be pregnant and I’m feeling some symptoms but it’s a few days to early to test.

How did y’all feel before y’all went into labor? I’m having no contractions at all but a little back pain and I’m feeling super sick and nauseous. Also very sore legs. Not sure if this is just a normal part of pregnancy or maybe early signs of labor? I’m 40 weeks
