I am 15dpo. I am certain of when I ovulated. Af due yesterday and I'm not normally late. Today I have been cramping, nauseated and feeling twinges and pulling in my tummy all afternoon. This led me to do an internal cervical mucus check which is normally creamy white at this time but today is a very pale brown colour and very sparse. Nothing on knickers. I feel totally wiped today. I can't help thinking this is late implantation, which would explain the bfn's I've been getting so far.
Anyone been in similar situation?
