- Utrogestan has no effect on baby if you are breast-feeding, as maximum concentration is in uterus.
- I would advise you to get a blood test for HCG. If it is positive, and more than 1500 IU you must ensure by transvaginal ultrasound scan (TVS) by an experienced sonologist that the pregnancy is not ectopic (outside uterus). In fact, in such an event if there is no gestational sac within uterus, the blood test needs to be repeated after 48-hrs and results will help guide further management. Also a TVS is better than trans-abdominal scan for visualising early pregnancy – gestational sac may just be within uterus.
- It is too late to think about it now. You should have used some good contraceptive. However, if the pregnancy is normal (intrauterine) I suggest you stop breast-feeding your baby. Also, the 8 cm fibroid may cause problems - spontaneous abortion, preterm labour, or other problems related to fibroid (red degeneration), or if pregnancy goes to term – mal-presentations, and problems due to fibroid post delivery. However, many women continue with pregnancy till term without problems - so you may be one of those.
