Confused please help cycle issues?

Cy
So let me start by saying my cycle this month was very wierd! I started out after my cycle last month two weeks later I started bleeding again but only for two days and lots of brown then it stopped here I am about 3 weeks later and lots of brown bleeding and some red but I started right after sex! I didn't get much signs of ovulation this month just the brown bleeding in the middle of my cycle which I thought was a sign! And no period yet it's all wierd someone help?
