What are the necessities of early pregancies.safety and care?

A few things.: Most importantly, don't smoke , drink alcohol or use drugs. Deep sea diving, sky diving, roller coasters or water skiing are not good ideas either. Hot tubs and saunas are ok only if the temperature is less than 100 degrees. Most other activity and exercise is fine to continue at a level you are accustomed to. Plenty of rest, stay hydrated and eat healthy.See your doctor. Congratulations!
