Sooo AF came april 27 and lasts about 5-7 days. It's June 19th and no sign of AF I have been cramping since the 22nd of May. The pain sometimes Mild and sometimes I have it much worse. It's not constant everyday but every other day or so till about this past Saturday. I've taken a PG test the 5th and 14th of June and both came our negative. :/ I don't know what to think or do. Should I go to the dr? BTW AF is irregular in December - 30th, January didn't get it, February - 10th, march - 22nd, April - 27. Those are the dates I've received AF since I got it April 27th I figured I'd be off a couple days since that's how it's always been. Well it's been more than a couple. I just need some advice or reassurance or someone to tell me something.
