TTC and late light period or implantation??!

Hiya I'm Taryn, I'm 23 and me and my partner have been ttc for a few months now.

AF was due 27th Jan, nothing, then 30th I had some really thick white tacky CM in my underwear and on the 31st started spotting pinkish blood nothing like a period tho I haven't even had to wear tampons or pads it's only when I wipe after using the loo.. then last night and today (Feb 3rd) it's turned very faint brown. Along with this I've had cramps unlike pms, all sorts of mood swings (even cried watching TV), temperature, a little nausea, extremely tired all the time now? I'd love some input/feedback

Thankyou ladies x
