It's definitly hard not having all the answers, or knowing what's going on... unfortunately there is so much out of our control. The body is miraculous and a tricky little thing

so I hope you're not super stressed or worried. It could be totally normal for you as much as it may seem alarming or scarey it could just be nothing

every pregnancy is different, every woman is different... so try to relax mamacita! Hakunametata... means no worries!
Good luck and hoping for a widdle heartbeat or something on your u/s!
