please help 😢 having a rough week

sooo my husband and I are on the outs. we finally came to an agreement tonight that we can "see what happens" if I go to a therapist (even though he's definitely part of the issue, I'd do almost anything to save this family right now) 😭 it really sucks right now. we have a 13mo and I'm 13 weeks pregnant. I'm worried the stress of all the arguing and upset during this week may cause a miscarriage. I've literally cried most of yesterday and today. I was concerned about it before but tonight I've had some mild cramping. not like period cramps, but noticeable and haven't had any cramps since about 5 weeks. please, ladies, I need some reassurance that everything will be okay. my next appt isn't for 3 more weeks and no ultrasound next time, only doppler for heart beat. 😔
