I just had a period this month and I have a ovulation calendar and well we've been having sex and he does in me and it's weird I didn't get my period again but I bleed for about an hour not even I am on birth control, I'm stopping what do I do? And why did I bleed the day before it says I should be ovulating

1. There are 100s of possible reasons
2. if you are on birth control (post was confusing) stop taking it, if you want to conceive
3. when you stop birth control it can effect your monthly cycle while your body adjusts
4. many women do not ovulate according to a online chart, they are really worthless if really trying to conceive. You need to be actually testing for ovulation to know when you ovulate

You're trying to conceive, but you're using birth control? How does that work?
