Anyone else, just overly worried and curious.

So I tested positive at an estimate of 3 weeks and 5 days, doctors in my area kept telling me not to get my hopes up and retest with home tests weekly until my ultrasound. I got my positive test on the 8th of February. I got a dye stealer a week and a few days after that, my fiancé thinks that we could have twins. He's got twin girls, and my family has a history of twins. But did anyone else get a positive before 4 weeks and it wind up twins? I only ask cause I like to over worry about everything I won't know anything for sure until March 14. I had started to get symptoms two days before I tested positive those symptoms (breast tenderness mostly) have only turned into no appetite and nauseated at strange smells I have been over the top with wanting things to be clean and needed a nap every day to make it to bedtime.
