Of course, mind-body connection is very strong and phantom symptoms happen to the best of us. But don't guess. Just buy a test kit and find out, or get a blood test done. Save yourself the mental stress.
Oh absolutely, phantom pregnancy symptoms are so real, especially when you are tracking every single day of your cycle. I remember feeling nauseous and dizzy before, only to get my period. Looking back now, our minds are incredibly powerful, so try to distract yourself.
Yes, thinking too much can definitely make you feel bloated or tired. The simplest solution is to avoid Google and just wait for your missed period to do a home test. Spending too much time researching only increases anxiety.
Honestly, when you have a busy work schedule, you notice fewer symptoms because your mind is occupied. If you are constantly symptom spotting, try to focus on your routine. Just do a urine test on the day of your missed period, no point over-analyzing.
When you are desperately trying, your mind can play tricks and make you feel symptoms that aren't there, I know how painful that hope is. But please don't be hard on yourself. If you've missed your period, a simple blood test can give you the real answer safely.
