When did she ovulate?
Even if you know exactly when she ovulated, there’s no way to tell if she’s pregnant without a test. If she’s exhibiting symptoms, have her go pee on a stick. Most tests are sensitive enough that a mere four days isn’t going to be too soon to register a positive result. If you’ve had sex throughout her cycle and used no birth control, chances are quite good that she is indeed pregnant.
Sometimes sperm can survive inside a woman’s body for several days; when attempting to get pregnant, I was told by a medical professional that 1-5 days was normal, but that even 8 days have been recorded. About ovulation and the cycle, a personal anecdote: when attempting to get pregnant for the third time, I was peeing daily on test sticks to detect the ovulation. Even though I’d been quite regular (ovulation around day 16) before that, in the cycle which eventually lead to conception, my ovulation suddenly took place on day 8. Merely two days after my period had ended. Later, the ultrasound measurements of the foetus confirmed it. (And yeah, that’s one bit of TMI I’m certainly going to burden my kids with before they reach the age when they start getting ideas about “safe” days.) I imagine the stress you must be going through, and the way your trust has been violated makes me wince. Nthing doing the test – pick a sensitive one, and repeat the test after a few days if it turns out neg
You can’t track your cycle (accurately) with a website – you need to track your cycle by recording basal body temperature and other physical changes like cervical mucous and position. And evey then, it’s an art, and not 100% effective. Based on her previous cycle lengths, I would guess that she probably ovulated some time between December 22 and 28, although that’s really just a guess, and timing can vary significantly for certain women. She certainly could have ovulated earlier. She can take a pregnancy test today, but if she gets a negative she needs to retest up to a week after her period is due – false negatives are entirely possible this early on. Also, this is a totally ridiculous situation, and I hope you know that. As a man, it is your responsibility to wear a condom unless you 1) completely trust your partner, 2) have both been tested for STDs, and 3) are prepared to deal with a possible accidental pregnancy.
Myself as an example: I am currently trying to get pregnant (yes, my husband is aware of this). I’ve been closely tracking my cycles for the past 6 months. I’ve been on fertility drugs for 2 cycles. My non-fertility drug cycles (6 cycles) were usually 28 days but could be anywhere from 24 – 32 days long, and ovulation that usually occurred on day 16 but could occur anywhere between day 11 and day 18. Sometimes I bled for 3 days, sometimes for up to 7 days. While I can almost always tell when I’m fertile (cervical fluid. ovulation pain) counting days is of little to no use for determining fertilility.
