Last period had it December 20th-26th.
I had sex jan 9th . He came in twice.. without pulling out.
I'm not on birth control..
My period is sometimes irrregular.
I just want to know the posibilities of me being pregnant.

If I am GREAT (: ill be the happiest person!
I just want to know what do you guys think?

It is not possible to say, want "odds" flip a coin, some people will have sex going by schedule of fertile times for a year and not get pregnant, others time, two people the first time they have sex, no watching days or time and they get pregnant firs time.

Of course pulling out is not a method, it merely lowers the sperm count, but since you did not pull out, it increases the odds.

The period being irregular is one main issue, since it will be had to track fertile times.

So you will need to still wait a bit and do a test after the time for your next period

Unfortunately, you are going to have to wait for your period to either show or skip.

If you miss your period it's best to use first morning urine to test.

While it's possible that you are pregnant since you were not using any form of birth control, it's hard to say if you are unless you know when you ovulate.
