My last lmp was aug5th it lasted until the 10th but fully over on the 11 I had intercourse the 13th 14th 15th 16th using the pulling out method today I'm having light bleeding could it be a sign of pregnancy

For your future reference pullout method does not work since there is semen in the pre-ejaculatory fluid.

So I could b pregnant right now?

Yes, but go to tyour doc and get a blood test

Whenever you have sex there is the possibility of pregnancy, protected or not. The withdrawal method is NOT a form of birth control.

So, yes, even though it is a slight chance, due to your last period, it is possible.

yes, but go to tyour doc and get a blood test

That was only 6 or 7 days ago. Too early for a blood test or any test for that matter.

You could be pregnant. Anytime you have sex there is a chance of becoming pregnant especially if your only method of birth control is the pull out method, which is not a method of birth control. According to your dates you did have sex around the time you might have been ovulating, which increases your chances of becoming pregnant. However, every woman can ovualte at different times during the month.
It is too early to tell if you are pregnant, and too early to start having symptoms of pregnancy. You have to just wait and see. If you miss your period that will be your first true sign that you might be pregnant.
If you are not pregnant and don't want to become pregnant I would suggest using some form of birth control.

Now the light bleeding is gone was it implation bleeding?

No way to know until you get that positive or negative result. But I can tell you that implantation bleeding is really very rare.

You may get cremping with implantation

I did have a little cramping but I only I had that light bleeding for a few sec then it went away it happen 1day

pulling out = worst form of birth control.
remember, or tell your significant other, that he , "ALWAYS DRIBBLES , BEFORE HE SHOOTS"!! And the male sperm can survive up to 5 days inside a woman's cervix. And it only takes one of the thousands placed there to fertilize an egg.

Mowerman I had to spread the rep but I am still laughing about your quote "you always dribble before you shoot". So true, but when will everyone else understand this?
