Am I really pregnant? Anyone experience false positive before?

I tested positive twice using a test kit. I'm expecting to meet my gynae this Friday for a blood test to confirm. The obvious symptoms I'm facing now are tiredness (feel tired even after nap) and sore breast. I don't feel nauseous, and tbh, i dont feel pregnant as well. You can say im a worrier, but before getting the results from my gynae, just wanting to hear the experience from the community whether anyone experience false positive before so that i can manage my expectation. This is my first time, and my husband and I really want a child badly. #advicepls #firsttimemom #pleasehelp #newbiehere
