Hi there, I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) As You were taking the pills regularly and continuously, chances of getting pregnant are almost nil.
3 ) Your symptoms can be due to
hormonal contents of the pills.
To clear the dilemma about
pregnancy, I will suggest you to get morning's first sample of urine tested for pregnancy.
4 ) As on now, please seek prescription support from your treating doctor for getting anti emetics and antacids, to control your symptoms.
5 ) Usually, you will start your periods within 3 to 10 days of finishing the pills.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar.
