Should i be concerned about right sided pain in my low abdomen during early pregnancy. it can make me feel sick but i can work through the discomfort ?

Pain in early preg: One sided pain is always of concern in a early pregnancy due a concern of an ectopic pregnancy. I suggest blood preg test, and pelvic sonogram.

Yes: Until it has been established that your pregnancy is located inside your uterus, you may need to worry about an ectopic, or tubal pregnancy. At 6 weeks after the first day of your last period, an ultrasound should be able to establish whether the pregnancy is in the correct place or not
