I got my wish of 3rd pregnancy but did I really want it? ?

These quizzes should have a “im not sure” option. I thought the app would help my mind/decision. I don’t know if I’m 100% pregnant, (pos test; got bloodwork waiting). MD said “maybe it won’t be viable” ? trying to cheer me up. I don’t know if telling husband and parents will cause massive outrage. So don’t know if going thru with pregnancy. I have 5 & 6 year old. Parents help a lot and are exhausted and husband said he’s done after two. I’ve always wanted a 3rd but it should have happened 3 years ago. I’m 36, my house is only 3 bedrooms and Hubby and I haven’t been on best terms lately. I’m so stressed and feel guilty hoping it’s not viable at times but blessed at same time. Maybe I should revisit when I’m decided. LOL. ?
