Hi, I'm currently 7 weeks pregnant and not sure if it's OK to be standing on my trip to work to and fro, for 1 hour each. I tried to stand for the whole trips one day and got anxious because I felt pressure in my lower tummy and my legs felt uncomfortable. Asking for a seat is always terrifying for me because my bump isn't clearly visible yet. Anyone has ever been in similar situation? I would really appreciate any information..thanks!
