6/28/16 AF IS DUE

I'm praying and fingers crossed that this is our month for baby #2! Ever since I've been off of my birth control the nexaplanon implant which was last year July 8th to be exact. I've had normal periods. I have a 25 day cycle average and last for 4 days!  But it's likes i experience pregnancy symptoms. Whenever af is two weeks away. And then the usual cramps I have a week prior doesn't start until 2 days before not as intense as it use to be but I notice it slightly. Anybody had trouble conceiving after getting off birth control?
