Is it all in my head rn?

Mary

Sooo. My period is scheduled for a few days from now. This past month i still cramped at the normal time. But my nipples were 1736337 times more sensitive, I was way more emotional, and my boobs legit look and feel heavier. You can even see my stretch marks are more visible on them (cause of the weight on them). Even my fbd said something. Am I possibly pregnant or just overthinking cause I want a baby so bad..?
