HeymisA - last month I swear I had implantation cramps going on as I remember them so know I thought, Clomid can be a pretty cruel mistress when it comes to mimicking post O symptoms, but I'm hoping in your case it's not and a BFP is on its way !!
For me I surged on new yrs day says my Dr so getting blood to him around this time was very hit n miss but just waiting around to see if its a new month or a BFP!!
Wishing you all 2014 babies sooner than later
