I tok Depo-Provera for the first time I had sex after one day I have atrial fibrillation which sometimes I notice and sometimes not. What should I do - just wait and take the next regular dose or take a chance and take one now.?It has been 7 hours since my last dose. I just came up the stairs - my BP is 107/66 my pulse (which runs fast sometime - usually slow at rest) is112 - no arrhythmias at this time.- Now I laid down for about 3 minutes and vitals were -106/78 107 pulse no arrhythmias next117/75 pulse 111 no arrhythmias -so my pulse is running faster than usual at night.I do not remember whether or not I took my Digoxin .125mg or not?
