Could She Be Pregnant? Risks After Unprotected Intercourse

Can I get pregnant?

My girlfriend's menstrual cycle is usually 30 days, with a possible variation of 2 days.
Her period started on November 11 and ended on November 16.
We had unprotected intercourse on November 19, but there was no ejaculation; it was just penetration and friction for about 3 minutes.
Prior to that, we engaged in manual stimulation for about 2 hours, and both of us reached orgasm.
Afterward, we cleaned up.
On November 26, we had unprotected intercourse again, this time with multiple instances of friction lasting about 3-5 minutes each, totaling around 4-5 times.
Five hours after this encounter, she took an emergency contraceptive pill (Plan B, 1.5 mg).
Since then, she has been experiencing dizziness, headaches, and increased vaginal discharge, which lasted for just one day.
Currently, she has breast tenderness that is still present and painful when pressed.
Recently, her appetite has increased, and her discharge has returned to its usual state.
What are the chances of her being pregnant? I apologize for bothering you again, but I wanted to clarify my previous question.

More Info

Based on the details you've provided regarding your girlfriend's menstrual cycle, the timing of your sexual encounters, and her subsequent symptoms, it is important to understand the potential for pregnancy and the associated risks.

Firstly, your girlfriend's menstrual cycle averages around 30 days, with some variability. This means that ovulation likely occurs around 14 days after the start of her last period, which would be approximately around November 26. The sexual encounters you described on November 19 and November 26 were both unprotected, with the second encounter occurring close to her estimated ovulation date. This timing increases the likelihood of conception, especially since sperm can survive in the female reproductive tract for up to five days.

You mentioned that after the second encounter, your girlfriend took emergency contraception (Plan B) within five hours. This is a crucial step as emergency contraception is most effective when taken as soon as possible after unprotected intercourse. It works primarily by delaying ovulation, preventing fertilization, or preventing implantation of a fertilized egg. However, it is not 100% effective, and the effectiveness decreases the longer you wait to take it after unprotected intercourse.

Regarding your girlfriend's symptoms—dizziness, headaches, breast tenderness, and changes in discharge—these can be early signs of pregnancy, but they can also be side effects of hormonal changes due to the emergency contraception. Plan B can cause temporary side effects such as nausea, fatigue, and breast tenderness, which may explain her symptoms.
To assess whether she could be pregnant, it is advisable for her to take a home pregnancy test. These tests are most reliable when taken after a missed period, but some can detect pregnancy as early as a few days before a missed period. If she experiences a delay in her menstrual cycle or if the test is positive, she should consult a healthcare provider for further evaluation and guidance.

In summary, while there is a possibility of pregnancy given the timing of your sexual encounters and the fact that emergency contraception was used, the symptoms your girlfriend is experiencing may also be related to the hormonal effects of the emergency contraceptive. It is essential for her to take a pregnancy test and consult with a healthcare professional for personalized advice and next steps.
In the future, to reduce the risk of unintended pregnancy, consider using reliable contraceptive methods consistently, and discuss options with a healthcare provider to find the best method for both of you.
