I've recently had the worry that I might be pregnant. If you're stressing about it, can your body create symptoms that make you think you might be pregnant? Like can it play tricks on you, making you think you are?
I've had the symptoms of my breasts being really sore and tingly, the Montgomery's Tubercules are more visible now, I've been sick at my stomach, I've thought I've gained weight, I've thought my breasts have gotten bigger, and the list goes on and on. So do I just need to quit stressing about it for these symptoms to go away? I should get my period in about 10 days, and my thoughts are if I don't quit stressing about being pregnant, I won't get my period at all.

yup!

A good friend of mine had a sex with with one of her friends and swore she felt preg right away-- but wasn't even preg!!! She stressed herself out for nothing.

yes if you keep thinking like you pregnant your body will act just that way that's why everybody tell you not to stress over it cause your body will act like it's pregnant even if you are not
