Am I wrong about being cautious?

Destiny

My partner and I have different perspectives completely. I had a miscarriage in Jan of 2021 and am now 6 weeks pregnant. Im trying to be cautious to not put the baby at any risk of my body rejecting it this time. Im extremely focused on not lifting too much, getting too stressed, or putting too much pressure on my tummy (all things hard to do with a 2 year old). I've been extremely angry this pregnancy and have the nausea to match, the only time im awake im trying not to yell or puke. But he gets mad saying im living like im broken. I tried explaining that im determined not to loose this baby this time. I've explained that this is all normal stuff and im not being overdramatic about it because this is the most fragile point in a pregnancy. But because his friends are rough and tumble he thinks im using it as an excuse. I told him I was uncomfortable lifting stuff above my head or lifting things over 20lbs (to prevent this baby from having its cord around its neck like my daughter had) and he got mad talking about how his friend currently in late pregnancy was mowing the lawn while pushing her child on the handles of the lawn mover. He also said something about me going back to the gym but when i said i cant work out to the same degree he got mad and said he knows for a fact pregnant women can work out, totally disregarding the fact that I can't take off and run 20 miles or that im getting tired walking up the flight of stairs to get to our apartment. Why should I be expected not to be a little more cautious? Why is he trying to push meike this? Why is he acting like these changes are nothing or dont effect me just because his friends have talked to him about it? Idk, its starting to actually depress me.
