Twitching and fluttering


So after miscarrying in May, we started to TTC again these past 3 weeks. I woke up so irritable yesterday for no reason and was just cranky all day. Also, the past few days it feels like my uterus is twitching or fluttering which is so weird. I’m like maybe it’s a sign that I’m in early pregnancy. I googled it and it said these are symptoms but I want to wait until my missed period to take a test. Should I just take a test to find out or wait? I’m not supposed to get my period until 11/21.
