Hello,
Thanking for posting your query.
You have mentioned that you are pregnant since 27th of April 2011 which means you are almost 2 months pregnant.
I did not understand what you meant by 8 month and 2 days pregnant?
Rh incompatibility does not interfere with travelling.
You can travel to your parents' place.
Follow these instructions:
Please travel by a Four wheeler, a car should be fine.
Please do not sit in the front seat, sit in the back seat.
Wear your seat belt.
Avoid jerky roads.
Do not travel at a stretch for long time.
take breaks in between.
finally, Do not travel frequently especially after 6 months.
Hope I have answered your query.
You can post your further queries if any.

pregnancy.
Regards.
