Hi, if you came to my clinic with those complaints I would ask you to stop worrying. Many women that start using the pills for the first time experience similar problems.
I understand that you have taken the inactive pills first and then started on the active pills. Also, you have had had intercourse only after your period was over that is about 11 days ago. The chances of pregnancy
occurring after a single act of unprotected sexual intercourse are only 4%. Also for women that have regular periods the chance of getting pregnant is more if intercourse occurs after 11-12 days since the first day of the period. Hence the chances of getting pregnant are low if you have had contact before this period.
You are also having a sick feeling in the stomach and most probably a cramp like feeling. This may be due to the pills as some females take time to get adjusted and may improve with continuous use and by taking the pills with food.
The pills are not known to cause any major effect on the baby if they are inadvertently taken in early pregnancy.
Since you have started taking the active pills late, I would recommend that you use a backup contraceptive
measure like condoms, for the next 7 days while you still take the pills to avoid pregnancy.
I would be pleased to answer any further queries that you may have, enjoy a wonderful day.
