TTC asap

We are TTC. I need help tracking my ovulation and which days are best to have sex to conceive. (We usually have sex at night) Please keep that in mind when responding.
My cycle is very regularly 32-33 days. Period lasting 5-6 days. My period started Dec 4th in the morning. I would really like to conceive as soon as possible. Those of you that have the same cycle please help!
Also, anyone who uses ovulation tests where can you get cheap kits? And do they work?
