Hmmm? Help

Shawna
So, I have had problems with my period since the very beginning. I got my period when I was in the 3rd grade! My doctor finally got my periods under control after years of test and 10 different forms of BC (YES I SAID 10) the last pill I was on was the 91 day pill , and I was told I'd only get my period once every three months, instead of 2-3 times a month. I used to throw up, be in intense pain, the whole shebang. Well I got it for 22 days straight. Very heavy. But now ... It's regular!! But I'm supposed to be ovulating now, but everyday I check my CP and it always feels firm with a little dip (like small opening). What does this mean?
