I just started birth control. Is what I am feeling pregnancy or BC symptoms?

Published: July 06, 2025
Dear TeenHealth FX,
I started taking birth control 11 days ago on the day 16 of my cycle and today (7/5/25)I started having a very sharp pain on my R breast and then I just started having the pain on both sides of my breasts. Is it posible that it could be pregnancy if I had intimacy on the day 18 of my cycle? or its just the birth control? is there anything I can do? or could it be something else non related to pregnancy ? or the pills? how could i know?

Dear I just started birth control. Is what I am feeling pregnancy or BC symptoms?,

TeenHealth FX understands how concerned you may be. Unfortunately, we cannot diagnose or treat over the internet. That is for your safety since we cannot grasp the scope of the whole situation, so we highly recommend that you see a doctor as soon as possible. A doctor will be able to understand the whole picture of your situation and treat you to the best of their ability. 

TeenHealth FX does think it is important for people to recognize that when on a new medication, especially birth control, it takes about 2-3 months for your body to adjust. Depending on the form of birth control, it can take longer than 3 months. Since there are different types of birth control each does go into effect at different times. For example, the birth control pill begins preventing pregnancy after a minimum of 7 days consistently. Please read the symptoms below of the birth control pill as your body is adjusting.  

Some adjustment symptoms (for birth control) are:

  • Breast tenderness
  • Nausea 
  • Mood swings 
  • Cramps 
  • Headaches  

We still highly recommend seeing a doctor so they can take a closer look and keep track of this. If pain continues past the adjustment period, then you may need to change your birth control.

If you need help finding a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist.
