Hello, and I hope I can help you today.
The mini-pill, or progesterone-only pill is less effective than combined (both
estrogen and progesterone) oral contraceptives in women who are not
breastfeeding. Combination pills are 99 percent effective, while the mini pill is only about 90 percent effective, meaning one in ten women will conceive while taking this type of pill per year.
However,
pregnancy cannot be diagnosed based on symptoms, because progesterone is produced during pregnancy and the progesterone-only pills can also cause
bloating, breast tenderness,
fatigue and irregular bleeding.
So there is a possibility you have conceived, so i suggest purchasing an over-the-counter urine pregnancy test. Modern pregnancy tests are very accurate, and will become positive within 10 days to 2 weeks after conception.
If you are not pregnant, your side effects may be due to the pill, and you may want to discuss an alternate birth control method with your local physician.
I hope I was able to adequately answer your question today and that my advice was helpful.
Regards,
Dr. Brown
