Should I be doing this?

One of my jobs requires me to lift heavy things and I'm about 4 weeks preggers. Before, I wouldnt have been worried but I had a mc in December and now literally everything I do scares me. I dont want to lift things, I dont want to have sex, I dont even want to drink the same teas I drank the first time because I'm afraid those caused my miscarriage.

Could someone just tell me to stop being such a pussy and that lifting things and doing my normal day to day things is okay? 😅
