I’m using my husbands log in but here goes.
I mountain biked up until the day before I went into labour. We live near the lake district and continued to mtb on our favourite trails there then when I got massive we went to more trail centres as I could go round the red-black runs once then have a sit in the cafe while my husband went round for another loop.
We had to move the saddle forward, raise the stem and put some more air in the rear shock nearer the end. The shock has been tf tuned since. We managed to bottom out my husbands shock when he gave me a backie around my village.
I really love mtb and continuing kept me healthy and fit for labour. I had a very easy home birth.
I also kept walking and swimming.
Since my daughter has come the biking has tailed off (sadly) but the walking continues and the weight has come off a lot easier as I kept my fitness up in pregnancy. We have a tout terraine single trailer now so we can get the little one out with the bikes.
Mtb is part of who me and my husband are and something we hope are daughter will enjoy when she is older. It felt very natural to continue throughout pregnancy.
I mostly stopped doing drop offs when I was 6 months (the odd small one didn’t hurt) and would push down anything I thought I could possibly fall on. I did get lots of funny looks from people when I was out, nobody was rude to me (which I was worried about) and lots of men were very shocked when a heavily pregnant lady passed them on the downhill/uphill sections of trails.
It was the red at Llandegla that I rode the day before I went into labour. I know its an easy trail but it was no problem at 38+2 weeks pregnant.
Good luck and keep it up.
