Travel issues. To take during travel?

You can travel to hill stations, but should refrain from climbing and mountaineering activities. The second trimester is relatively the safe period in a pregnancy, compared to first and third trimesters. Make sure you do not over-exert yourself, and catch up on sleep and rest, lying on your left side. If you feel breathless, please seek medical advice, as oxygen supply to your baby depends on your level of oxygenation. It is also better to avoid any long and bumpy road trips. Remember to keep yourself well hydrated with plenty of water and fluids. It is better to avoid street food, and unhygienic food, as that can be a source of infection. Please avoid sedentary postures for long periods, and do leg and foot exercises at one to two hour periods, to avoid blood clotting inside your veins, which can be potentially life threatening. Keeping well hydrated will also help to prevent clots, along with preventing urine infections. You can also take Aspirin (75mg) after meals, once daily for five days, starting two days before your trip, if you wish to further reduce the risk of clotting, provided you are not allergic or intolerant to Aspirin. I am assuming that your pregnancy is so far uncomplicated, and as you have mentioned, you have no medical conditions. Have a good and safe trip.
