7weeks Pregnant, told my friends about it but seems like i have created more stress for them. How?

First time pregnant.. Told my group of close friends (3 married ladies, 1 with 2 kids, 2 still trying) the news that im pregnant. Though they congratulate and are happy for me. But i recently got to know from the friend with kids that the other 2 are feeling stress after my news. I dont know if i should/can still ask or share things about my pregnancy to the my friends now? Like we are so close and can talk abt anything but now i feel if I share then will add stress to my friends. So im feeling abit sad.. Cant continue share happy things with friends.
