Ladies who have been pregnant or are pregnant now:

I need help!! Lol. Have any of you experienced a major delay in getting a positive pregnancy test over 3 weeks (or about) after your missed period??? If so, how long did it take for you to get your positive or did you just do a blood test? I would've gotten a blood test by now but I'm worried I will get AF as soon as I do! And worried that the blood test would just be negative too. Do you know what caused the negative pregnancy tests for so long? I feel different. I know many times we want it so badly that we may imagine "symptoms" but too many things are happening that I know I'm not imagining. My breasts (especially nipples) have been extremely tender and sensitive for about 2 weeks, I have had creamy cm on and off for 3 weeks, moments of dizziness when sitting or standing still, and sensitivity to scents/foods. Thank you for your help/opinion!! <3
