my first period took 9 weeks to come after stopping! my periods have NEVER been regular though (thats why started the pill back in high school). went to the dr telling him this (as my next period hadnt come after 7 weeks... un beknown to me i was pregnant.. thats why) and apparently there is something u can take to make ur periods regular but still able to conceive. wouldnt know the name of it as in the end didnt need it but its worth asking ur doctor...
