So this morning around 6.30am i woke up to a pinching pain in my right side that lasted not very long and thought nothing of it. This afternoon when i went to toilet there was a tiny streak of blood on the tissue when wiping and since then there has been nothing. Could this be implantation.? I got a very clear positive opk on the 12th October and ovulated on 13th I know I ovulated as I had lots of ewcm and the pains. Took opk on 14th and was negative.xx
