I'm 24 I'm trying for my third baby. 10 months off the mirena coil 1 stone actually planning to conceive...

So currently in the 2ww. I'm on 10dpo. My AF is due on Friday the 7th. ..since the 31st I have had severe boob hurtage..not quite like pms. I have been feeling wet down there ever since ovulation and just feeling off and bloated I'm eating way way more than I should be. So I'm 10 dpo. And today I am currently suffering with sharp stabbing pains in my lower back and I checked my bits and I pulled out my finger and I have blood ..u just credit over not having any milk and I mean crying breakdown and it's usually a sign that I'm due for AF if I have a sudden cry but over no milk 😢 I have attached pics Its of my cycle and of a wipe with the light blood from today .. ps it's doesn't smell like AF blood... but after I check my Cervix I get a sudden pain in my uterus and been getting cramps since day 1 dpo.

Any advice or thought please as I'm really confused is my peripd early surely not by 3 days
