If you found out you were pregnant while you were still taking the estrogen-progestin pill or another combined oral contraceptive (COC), contact your gynecologist or someone from the women’s health center right away, who will probably give you an ultrasound. Afterwards, you can discuss together all the aspects of the case, and decide what to do, obviously in accordance with your partner as well. The hormones contained in a COC are not usually a problem for the fetus. More than anything else it will be important to remember if you took any other medicines or got any X-rays when you didn’t know that you were pregnant.
