Please I took both tablets of postinor2 at once Feb 2015. Being having irregular flows since then. My interval is usually 30days but being having 22 days..58 days..62 days..26 days..66 days.. 29 days..and it's going to another two months for me again. I'm getting worried that this has affected my reproductive system and would like to know what to take to regularise back to status quo. Thanks.
