Is my gf pregnant?

[The_Dude_98]

Two days ago my gf and I had intercourse. I did not orgasm, pre-ejaculation at most. She had also missed one day of birth control, but we made love two nights after (before she started on her second pill after starting back). Now she says she had nausea, a head ache, and feels sleepy (she took about an hour nap). Is it possible to tell this soon? What are the chances that she could become pregnant from this?

P.S., she says she believes that it is from staring at a computer for too long, as she has been working on a project for her animation class at the university she attends. However she says it’s gotten really bad today. Other details include that she was also dizzy after I left her house that night, she was feeling congested yesterday, she visited the gynecologist yesterday, and we had 3-4 sessions of intercourse.

So is she pregnant (or at least a high chance) or am I freaking out over nothing?

Hello~The chances that your GF is pregnant is fairly slight. Just  missing one dose should not affect the chances too much, plus, if she is only a week or two a way from her next cycle, she is probably not ovulating anymore, in which case, she won't be able to get pregnant, a woman can only get pregnant while ovulating which is usually a week after her cycle has finished and she has a window of a few days to conceive. The following is what I have read regarding pregnancy and ovulation:

"The researchers found that the probability of a person getting pregnant rises sharply 7 days after the LMP. This probability of pregnancy is highest at 15 days and returns to zero by 25 days. For the women in the study, the probability of being within the fertile window was: 2 percent at day 4 of their cycle"

Another article states:  "One of your ovaries will release an egg (ovulation) about 14 days before your period starts. The first day of your period, when you start bleeding, is counted as the first day of your cycle. If you have a 28-day cycle, you'll usually ovulate some time between day 10 and day 15 of your cycle."

Also, it is very rare to start having the symptoms she is having so quickly. If she is concerned, then a trip to her gyn would be beneficial, I believe they have a pregnancy test that can be taken fairly early, and it is pretty accurate.

Thanks so much. Obviously I’m not too informed on medical knowledge when it comes to human biology, so this is very helpful.

Okay, so she had her period yesterday. This would be 26 days after her last one. I saw that an average period is 28 days, and only occasionally for some women it's 26. I also saw that a woman can have an earlier period if they are pregnant, but I also have seen from only a very few sources that it can be due to missing a day of birth control. So which one is the most possible: her cycle is 26 days, (if it considered early) she is pregnant, or (also if it is early) is it more likely that it happened because she missed one day of birth control? Keep the post from last week in mind.

Excerpt from Very Well Health - Can You Get Pregnant If You Miss a Pill? Inconsistent dosing can undermine the protective benefit...

"If you miss taking a birth control pill or take one at the wrong time, it does increase your chances of becoming pregnant. However, you shouldn't panic or assume that the protective benefit of treatment has completely disappeared. The drugs do have some "forgiveness" in that levels of the medication will remain in your blood even during a gap.

But it's important to remember that the pill is not infallible. While it is 99 percent effective in women who take the pill on time every day, that figure drops to 91 percent in women whose adherence is less than perfect.1 In the end, the risk of pregnancy increases the more frequently you miss doses and the wider the gap there is between doses. Even the type of oral contraceptive you are taking may contribute.

And if you miss more than one dose per cycle or pill pack, the risk of pregnancy can suddenly become very real, indeed.2"

I understand this, but what are the chances based on all symptoms? Also, she is a week or two away from when her next period is supposed to be
