"paragard was the first bc ever used at 27yrs old, after my second child. the first 3-6 months were horrible heavy periods but they adjusted to heavy bleeding the first 2 days of my period... 
everything was going great until 2 yrs later, now 29 out of no where i started feeling heart palpitations, trouble breathing, sweating. i figured it was high blood pressure and scheduled an appointment right away. i&#039;m perfectly healthy but was asked to get lab work done and also asked about my birth control....doctor told me that iud&#039;s cause heart palpitations. 
lab work came back with mild anemia, so now i&#039;m really bummed out because i no longer feel safe with these bc options, but also after doing some research, heart palpitations may persist after removal."
