Today I am anywhere from 5-7dpo. I've had cramping for the last two hours. Not as bad as AF, but it's a dull ache. Went to the loo and noticed pink tinged CM (which has turned into an EWCM consistency, just not a lot of it). It was literally a pinprick or two, and I've not seen any since. AF should be here in 7 days, based on my 28 day cycle. I've never experienced any implantation pain/spotting with my past pregnancies. Is it too early? Should the spotting be heavier for implantation?
