Stress, anger and miscarriage

For the couple past days I’ve been really stressed at work to a level that it’s affecting me badly and today I had a huge fight with my brother and his wife, she insulted me and my bro didn’t say anything, and this incident made super mad and stressed to a level that I wanna smash something

And I’m 6 weeks plus 3 days pregnant, I really can’t control my sadness now but plz reassure me that it won’t affect majorly on the baby!
