My suggestions:
1. Go to see your family doctor ASAP so that he may arrange all kinds of necessary test for you. IPS (integrated prenatal screen) is a must.
2. Listen to old sayings from grandmas about what you'd better not to do during early pregnancy, such as: do not lift up youself and try to reach something too high, do not drive (or take a ride) on a very bumpy road (e.g. Carling road)....
3. If possible, go to see a Traditional Chinese Medicine Doctor and ask some advices about how to pay attention on your food such that to balance Ying and Yang food.
Best luck.
