prenatal question.... Evening primrose oil.

[Rhiaberry]

Hey, so ive been taking mumomega this month, im all out, im unsure what to do next, buy a new pack or switch to pregnacare with omega 3.... the only thing is... mumomega has Evening primrose oil in it, which can help to concieve and supposidly to help bring on labour... iv googled this and there is not enough research against taking this during pregnancy as they dont know the effects. But the pack says 'before, during and after pregnancy'- as much as i like it, i dont know whether its just worth switchin to pregnacare, as im not getting not other vitimins i need... (i am taking a folic acid a day). So basically im asking all you opinions/experiances on this so when i go to the shop later, i know what to pick up. Thanks in advance x
