Stress

I’m 4 weeks and 4 days and am currently dealing with a lot of stress. I actually have a pretty much stress free live until I found out I was pregnant. Then boom my mothers husband is in a coma like state for 4 days in the hospital unresponsive. He has cancer and it’s gotten really bad just out of no where. Also we are selling our home which is a stressful event. I am so worried I am hurting the baby !!! I feel waves of sadness and so stressed until my body throbs. I haven’t told my mom yet because of what she’s dealing with . It’s just bad timing . How bad do you think this is on my baby ? My mother’s new husband who I never liked was pretty controlling with money and has kids prior to marriage so if something happens she won’t even have a house to live in or money to support herself . Which puts all the stress on my husband and I. Thanks
