Hi me and my boyfriend had sex on night of July 30 , he ejaculated inside of me, the next morning of July 31, we had sex again and he did the same thing.. now, on the same day of July 31 in the afternoon I got my period, this is also my expected period date, is there any possibilities that I may be pregnant? By the way, I have a regular cycle . Thank you very much. I am so worried please help me.

The odds are that you are NOT pregnant.
There is a slight possibility that if the bleeding doesn't have menstrual lining in it, that it is just thin blood, and light flow, that you could be.
Somehow, somewhere in the world, there is always someone who gets pregnant in the million to one odds, or thousand, or hundred.... or one in ten.
It's always possible.
But I doubt it.
That's not really the question.
The question is why do you put yourself through this awful worry by having unprotected sex???? If you forget things all the time, get the patch. Find a Planned Parenthood. All free or cheap. GO!!!

WOW. In today's age you have no knowledge of "how you get pregnant?
Re-read Joypulv please--"The question is why do you put yourself through this awful worry by having unprotected sex???? If you forget things all the time, get the patch. Find a Planned Parenthood. All free or cheap. GO!!!"

The odds are that you could be. Those little spermatozoa, hundreds of them are intent on reaching that egg. They move at their own pace, some faster then others, some wait for a chance.

So I may ask, why take that chance. Spontaneous copulation can be accomplished and enjoyed with proper protection and in many cases enjoyed more because of it,

Any time you have sex, pregnancy is possible, even with protection, even on your period.

You'll have to wait and see what happens with your next period. If you miss it, wait a week and then test using first morning urine. If it's negative, wait another week and test again, or get a blood test done.

If you want to lower the risk of pregnancy, use at least two forms of birth control. The pill and a condom are a great combination. If you keep doing what you're doing you will get pregnant eventually, if you aren't already.

Good luck.

I agree with the others... at this rate, you WILL be pregnant in the very near future if you aren't this time.

Doing what you have the way you have, its all a matter of when, not if.

In probabilities, there is no such expression as 'the odds are you could be.' I already said you could be. The odds are either/or, and you can assign percentages or not. It is my contention that you aren't.

Possible, but not likely. If an unplanned pregnancy would be a problem for you, lessen the possibility even more by using a reliable form of birth control, and have your partner use a condom... no penetration without one.

Keep in mind, even with birth control used correctly, pregnancy can still happen, so there will always be a chance, even if unlikely.
