Weird question

I had my midwife appt yesterday followed by loads of hideous mucus but I've woken up this morning and gone for a wee and I can smell like period blood but there's none there I don't know if I'm imagining it or if I should call up and ask I've had alot of back/stomach pain in the last few days but no timable contractions as of yet (I'm 36+4) my iron is fine and I'm not taking any supplements as that was the first thing that came to my head, I'm worried incase it's my waters leaking as I've had wet underwear for a few days now but it doesn't smell like urine and completely clear midwife said just excess discharge but didn't actually even look
