Answers:

If i have white blood cell and blood in my urine what is wrong wiyh me?

What your describing is the 'rhythm method' of birth control. If you start near the week of menstrus as week '1', then the following week is common infertile. The ovaries will produce eggs for fertilization around the middle of the cycle, so conception is more likely within week 3 and 4.

That said, unprotected sex is never a good opinion if you do not want to become pregnant, there are other subtle fluctuations. Additionally, use of condoms is important within limiting the spread of sexually transmitted disease. Unless you are in a dedicated long occupancy relationship always use a condom to prevent STD verbs.

Does it matter that im on my interval more than once in a month?

That depends if you want to return with pregnant! If you dont you should never be having sex short a condom or some other form of birth control.

Any good explanation?

it's better using condoms or pills if u don't want getting pregnant, but u have to count the days between 2 length and divide by 2, 3 days before and 3 days after u may gain pregnant the other days it's safe
