Can someone help put my mind at ease

I had my transfer on Nov 5th and although I’ve been told to not take a test until tomorrow when I tell the clinic, my impatience has got the better of me! I’ve been feeling symptoms that I had with my daughter so I’m feeling positive about it and have been from the start. However, my mother in law has twisted it and planted a horrible seed of doubt into our heads that the tests are ‘false positive’ and ‘I’m a liar and not really pregnant’. Has anyone else experienced this and can put mine and my husband’s minds at rest? 💕 (the last strip test is 13DPT)
