Chemical or false positives?

So on Wednesday evening I took a shop own brand test randomly and I saw a faint line but ignored it thinking it was probably just the way the indent was on this test. I took the other test from the pack on Thursday morning and again a line and it was slightly darker. So I brought some of the clear blue 6 days early tests and the first one I peed straight on with approx a 2 hour hold and if was negative. Then I waited 5 hours and took the other clear blue from the pack but dipped it and it has a faint line. I also took one of the shop own brand tests and it looks faint or probably bfn and I just was hoping to see something. So I took another one of the clear blue ones today after approx a 5 hour hold again and it has a faint line again, I also took a first response and a different shop own early results test and those two are negative (all same urine) I just don't kno what to think, 4 false positives or chemical or ectopic or maybe pregnant and just super early so sometimes tests are picking it up? 🤷 I don't know. Any help would be much appreciated and please don't be rude it's been a hard time 😔 thank you.

Oh and I'm not bleeding but increase in CM with some stretchy bits mixed in with creamy discharge
