I feel like I’m going crazy

Lea • I have a 10yo son and another BOY on the way! #Juneof20

I know I keep posting about symptoms but I’m just worried. I feel like mine have completely disappeared today. My boobs were somewhat sensitive this morning but now there’s nothing. Not even when I press on the sides of them. My nipples were sore last night and breasts pretty tender. I’ve had a miscarriage before and I’m a nervous wreck. I cramp all day, every day. No spotting/bleeding. Any words of wisdom or advice? I work on an ambulance and I have to pick up heavy ppl and equipment all day for 24hrs. There’s been other women work while pregnant and I know you can continue to do things during pregnancy that you normally did. I’m just scared.
