Recent Implanon removal help!

I just got my implanon out 12 days ago. I've had it since September 2013. I bled for five weeks the day after I got it and again the following December, but haven't bled a drop since. I've been crampy off and on and I had pink when I wiped twice on Saturday (two days ago), but no period. Hubby and I did the deed Thursday and Friday. I'm afraid I won't end up pregnant because I only see him every other week for two days... And I have no idea when my cycle will come back. It took us a year to get pregnant with our little boy. Any advice or success stories? Anyone pregnant straight off removal without a period?
