Had my mirena out exactly 7 weeks ago. Exactly 4 weeks ago I got my first AF in 6 years (due to pregnancy and BC) and all signs indicated I ovulated on CD14 (except BBT, cos I hadn't started). Now it's CD29 (usually 28 day cycles) and no AF. BFN 2 days ago, and have had PMS. I guess I'm sad/worried cos it seems to indicate that my cycles haven't returned to normal which I thought they had :-( it's pretty common for it to take a few months to regulate but I'm impatient! If I'm not pregnant now, then bring on my next fertile window so I can start trying again!!
