How long do I need to wait to take a test I got my Nexplanon out 3 weeks ago got on nuva rig but it wouldn't stay in so I gave up on it I have been trying to get a dr appointment to get on the depo shot but never seen to call when any one is in the office any way I had sex tonight and the condom broke don't have the money to get plan b ( not that im broke all of this weeks check went to fixing our heat) so when do I test so I know if I can get on birth control or not?
