hello doctor I want to ask that I used an I pill before 2 months ago now my periods are getting on time from the past 2 months and my periods are normal, but today am feeling
vomiting and my weight is increasing? does it means that I am pregnant?

Probibly means you have a flu or ate something that doesn't agree with you.

Have you gotten a positive pregnancy test result yet... if not then it can mean anything... most of them NOT pregnancy related.

There are no "symptoms" the first few months of a pregnancy... except a missed period in most cases. (false periods are actually very rare)

Don't worry, you cannot be pregnant if you have taken I-pill 2 months back and got 2 periods also. Check with your doctor if your vomiting does not stop. You may need some medical attention.
