7w5d pregnancy symptoms abating

It’s been about two days since I’ve had any nausea / morning sickness, fatigue is slightly better, and my breast tenderness is not as painful. I am still having mild cramping (not nearly like a period, more like what I imagine is uterus expansion) as I’ve had my entire pregnancy, no discharge or bleeding but I am terrified I’m miscarrying. I know that symptoms can come and go, but I just can’t help but doomsday…went to my first ultrasound last week and fetal heartbeat was detected/all was normal.

Anyone had similar experiences and can talk me off the ledge?? I’m truly just a ball of anxiety right now.
