Confused

Hello everyone this is my first time posting and hoping I do it right and get some answers because I’m confused... my husband and I have been working on baby number 3 since end of September... Last Wednesday morning I took a pregnancy test and it came out positive then I wanted to really make sure before saying anything so I took another one around 6pm and it came out negative 🤦🏽‍♀️ now I’m confused so the next two days I took another test different brand and they both came out negative. Today I was supposed to get my period and got nothing, I still don’t have cramps. Can you ladies help me? Am I? Or is mrs Mother Nature playing with my feelings and is coming when I least expected 😭🤷🏽‍♀️
