Can I get pregnant?


On October 27, I had unprotected sexual intercourse with my boyfriend for the first time, but since I couldn't find the opening, not everything was fully inserted.
On October 28, about 24 hours later, I took emergency contraception.
I experienced dizziness as a side effect for the next two days.
On November 4, I had sexual intercourse again, this time with a condom, but it was put on inside out.
I did not take emergency contraception this time.
During the first penetration, my hymen broke, and I experienced bleeding that lasted until November 6.
The blood was brownish and slightly red, and I'm unsure if it's my period or blood from the hymen rupture.
Starting November 3, I have had symptoms of lower abdominal pain and swelling.
On November 6, I also experienced breast swelling and pain.
My last menstrual period was on October 11, and my cycle is regular, so I expect my next period around November 11.
Could the lower abdominal and breast pain and swelling be side effects of the emergency contraception, signs of an impending period, or indications of pregnancy?

More Info


Based on the information provided, it seems you are experiencing a range of symptoms after engaging in sexual activity, and you are concerned about the possibility of pregnancy. Let's break down your situation and clarify the potential implications.

Firstly, you mentioned having unprotected sex on October 27, followed by taking emergency contraception (the morning-after pill) approximately 24 hours later. Emergency contraception is designed to prevent pregnancy after unprotected intercourse and is most effective when taken as soon as possible. The fact that you took the pill shortly after the encounter is a positive step in reducing the risk of pregnancy.

You also noted that you experienced some side effects from the emergency contraception, such as dizziness. This is not uncommon, as hormonal fluctuations caused by these medications can lead to various side effects, including nausea, headaches, and changes in mood or menstrual patterns.
On November 4, you had another sexual encounter where a condom was used, but it was put on incorrectly. However, since you mentioned that there was no ejaculation inside, the risk of pregnancy from this encounter is significantly lower, especially if the condom did not break.
Regarding the bleeding you experienced from November 4 to November 6, it is essential to differentiate between menstrual bleeding and bleeding due to the rupture of the hymen (the membrane that may bleed upon first intercourse). The presence of brown and light red blood could indicate old blood, which is often seen at the beginning or end of a menstrual cycle. However, it could also be a result of the physical trauma from the first sexual encounter, especially if the hymen was torn.

The symptoms you are experiencing, such as lower abdominal pain and breast tenderness, can be attributed to several factors. These may include:
1. Hormonal Changes: After taking emergency contraception, your body may experience hormonal fluctuations that can lead to symptoms similar to premenstrual syndrome (PMS), including breast tenderness and abdominal discomfort.

2. Menstrual Cycle: Since your last menstrual period started on October 11, you are approaching the expected date of your next period (around November 11). Many women experience symptoms such as bloating, breast tenderness, and cramping in the days leading up to their period.

3. Pregnancy Symptoms: While it is possible that these symptoms could indicate early pregnancy, they are not definitive. The most reliable way to confirm pregnancy is through a home pregnancy test, which can typically detect pregnancy about a week after a missed period.

Given your timeline, if your period does not arrive by November 11, it would be advisable to take a home pregnancy test for confirmation. If you experience heavy bleeding, severe pain, or any other concerning symptoms, seeking medical attention would be prudent.

In summary, while your symptoms could be related to hormonal changes from the emergency contraception or the impending arrival of your menstrual period, they could also indicate pregnancy. Monitoring your cycle and taking a pregnancy test if your period is late will provide clarity. If you have ongoing concerns or experience significant discomfort, consulting with a healthcare provider is recommended for personalized advice and support.
