... a common occurrence?? I am going to call my GYN tomorrow (of course, today is Christmas Day n they're closed... ) But should I be more concerned and IMMED STOP taking this pill?? I have had shortness of breath in the past (right after my son was born, it was post natal CHF from the long labor..) ALSO, COULD THIS BE AN ALLERGIC REACTION or is this more than likely associated with taking OC's??? Thanks for any info!!
