No symptoms all . (HELP)Except crazy mood swings ?!?

Jhanelle
I'm 6 weeks and it seems like my breast had gone back to normal size or just stopped growing ?!? Scared of a misscarriage but almost everyday me and my boyfriend get into it and it seems like I start the argument and I end up crying like 3-4 times each night   Is this a symptom ? That's pretty much the only thing assuring me that I'm still pregnant  😩
