Congrats on your pregnancy! While the recommendations have been for much shorter duration, current research doesn’t show any adverse effects if you have a normal pregnancy and I think that recommendations are changing (hopefully!). I went on long mountain runs during both of my pregnancies and was totally fine. This article is really well-written and reinforced my gut feeling that I wasn’t doing any harm: https://www.irunfar.com/2017/12/baby-on-board-long-distance-running-during-pregnancy.html
As long as you’re feeling good, keep at it!
