Thoughts ?

So my and my ex was in a long distance relationship. Last time we had sex was probably the end of April. I’ve had my period since then but it was a weird one and it was late. Now my period is 3 days late this month and usually I don’t worry about it too much. But for the past couple weekends every time I drunk alcohol I threw up which I never do. The last time it happened was Saturday and every time I smelled food I threw up again. I’m going take a test as soon as I get home. But I’m thinking I could be pregnant 😩
