Generally, no, the points contraindicated in pregnancy for acupuncture/acupressure do not apply to Tong Ren or other energetic based treatments. The needling/pressure contraindications in the area for hemorrhoid's in particular (low back/sacrum, etc.) have more to do with avoiding trauma to the fetus than any energetic reason. Whereas other points such as LV 3, which are contraindicated, are avoided due to the downward movement of energy that they create which could technically cause an issue during pregnancy. This is less of an issue with Tong Ren and other energetic arts as well, but strong dispersive and/or descending techniques points should be used with caution as a general rule during pregnancy.
For hemorrhoids then, you can tap on the following points:
T7 for the blood vessels, huatuo's of S2, S3, S4, and S5 (to clear the sacrum area), possibly adding in points such at GV 20 (draw the energy up the spine) and GV 17 (medulla/blood vessel issues).
