Unusual?

Aleah

Since high school I have had a regular cycle. But now recently (the last 6 months) my cycle has been so irregular, sometimes instead of being a couple days off either early or late.. I have been 3-4 weeks late. I take the pregnancy tests and are negative and then I end up getting it around when I'm supposed to get next one. So I guess I'm "skipping" periods?

Any ideas what's going on can't get in to Dr til end of next month

I should also add I am 29
