Does cramping really last this long?

[MrsG23]

Im roughly 9dpo ... Unprotected, drunken sex early last week - around ovulation.
Ive had crampy pains for 4 days or so and in the last 3 days, ive had a spot of brown blood each lunchtime, but only when I wipe.. This evening Ive got a bit of back ache and in the last few days, Ive been permanently aware of my right nipple. If touched, it hurts for about 10 minutes afterwards. Whilst writing this, I feel like ive got to rub it to stop the ache in it. SO odd.
BFN yesterday.. AF due sunday/monday..
is this typical of the myth that is implantation?? Going out my mind...

I'm in a similar situation Op but I've not had any spotting, just waiting to see if AF turns up on 11th :/ I still have occasional cramps, always nausea, very tired, eating little but I've also been diagnosed as prediabetic so arghh, so confused.
If you only DTD last week I'm wondering if you'd have implantation pain so soon? I hope somebody wiser comes along! x

Well.. I had sex Monday night.. the cramping started exactly a week later. And the bleeding has been on and off since tuesday - nothing all that exciting.. Just a smudge on the tissue once a day. 24hr of nothing at one point?
The last 24 hours, my right boob has been aching and nipple SO itchy.. maybe/maybe not? no idea!

Try testing again? Some tests are quite sensitive x

BFN this morning at 10/11dpo.. Maybe still too early? Cramping has dulled to more of a "full" feel, like aware of my insides - if that makes sense?

Ok, so no spotting or bleeding for nearly 48 hours now. Cramping has stopped too?
Just itchy, sore nipples! :(
