Having frequent headaches, feeling bloated and can't eat. What's wrong?

Male or female, age, sexually active?

I’m a female, 18 years old and yes, sexually active.

Pregnancy comes to my mind, then.

I can’t be pregnant because we used protection :( and it didn’t seem like the condom broke or anything like that…

Welcome to Fluther. No birth control is 100% effective. Even if you’re sure, go get a home pregnancy test. The first thing a doctor will ask is “are you sexually active?” and then order a pregnancy test.

Maybe you have the flu.

When did the symptoms begin, how long?

Obviously, nobody here can advise you, other than to see a doctor if they persist for long.

Headache is not usually a symptom of pregnancy, perhaps the bloating, the lack of appetite could go either way with both a virus or early pregnancy.

Don’t panic, but look at all possibilities.

Maybe IBS? In any case, get thee to a doctor.

See a doctor. Strangers on the Internet cannot diagnose you.
