Advice???

Hi lady just have a few questions and would like to hear wot you think

Ok so I have irregular cycle so I don’t know when I ovulate unless I track as it’s different every time but once I had ovulated and if I did conceive when implantation did happen could I still implant as early as 6dpo or am I likely to implant late ???

My reason for asking is because I have been having drown/pink stopping on and off but every day for 6 days now my boobs hurt I am falling asleep every time I sit down 🤦🏽‍♀️ and I am very irritated and moody over the last few days but still getting bfn I am currently on cd 48 x
