Irregular motions at 8 weeks pregnant

Hi, welcome to the ehealth forum and I am glad to help you.
You seem to be concerned by the constipation during pregnancy with present gestation of 8 weeks.
Due to all the increase in your blood supply and the unaccustomed activity in the lower abdomen, some women experience constipation around 7 weeks of gestation. It is fairly easy to correct by making sure that you drink lots and lots of water, as much as eight 8 ounce glasses a day and adding extra fiber to your diet. You can add the fiber by eating more raw fruits and vegetables or trying some of the commercial high fiber cookies designed specifically for relieving constipation.Daily walks and other aerobic activities can help prevent and treat pregnancy constipation.
Try to avoid caffeinated drinks (coffee, tea, colas, and some other sodas), since caffeine makes your body lose fluid and won't help with constipation.
Stool softeners are generally considered safe during pregnancy.Stool softeners, such as Colace, moisten the stool and make it easier to pass. The active ingredients in these products aren't absorbed by the body, so they're unlikely to have an adverse effect on a developing baby. Check with your health care provider, however, before taking any medication — including stool softeners and other types of laxatives — to treat pregnancy constipation.
Hope this helps. Take care.
