Advice please... Pregnant after 2 miscarriages

Jo
Hi all,
I normally dance 3 times a week (ballet, jazz, tap etc). I've been doing this (as an adult) for about 18 months. Just found out I'm pregnant and wondered if you would continue in first trimester if you'd already had 2 miscarriages (one while dancing one before i had gone back to it and was not exercising at all).
Not sure how easy I should be taking and whether all the stretching (forward and back bends) may be damaging if little one is at flight risk!
Please let me know what you think, don't want to have to tell my dance teacher I'm pregnant yet as still under 5 weeks so can't ask her! Xx
