Hi everyone

After long 4 years finally posting again, I'm a bit confused I'm peeing a lot, I'm hungry all the time , I got headaches basically daily and feeling nausea all the time...I been testing home pregnancy test but is very very faint line even after 5 days .. I'm 3 days late from my period but I had some spotting and little bit not heavy bleeding but only changed once and since then no heavy bleeding just lasted 3 days spotting make it says only when I wipe and I'm confused, my period are regular and normally heavy plus goes 6 days ... it's a bit unusual for me. Has it happened to anyone and had positive?

Should I test again ?
