I miscarried July 29th and finally started noticing some fertile CM last week. suspect I ovulated on Friday. We had sex every other day since Monday August 15th. I'm experiencing very mild cramps/twinges identical to the ones I had my last pregnancy before AF was due. Could implantation have happened already?? I feel a little lost since I've had no period since the miscarriage and feel completely out of control on my dates.
