I didn't know this, and I figured I'm probably not the only one, so thought I'd share it. Found it at http://www.babyhopes.com/articles/epo.html
Evening Primrose Oil or EPO should only be taken from menstruation to ovulation. This is because Evening Primrose Oil or EPO can cause uterine contractions in pregnancy. The dosage taken should be 1500mg to 3000mg per day. Since essential fatty acids are necessary, you can take flax seed oil in place of Evening Primrose Oil or EPO after ovulation. This may be taken throughout pregnancy as well.
