Lol thanks everyone. Reassured me a lot :).
Tests not years. Stupid autocorrect
It's classified as a category b drug meaning no years have been shown to have adverse affects on a fetus during any stage of pregnancy.
I've never been on it but I googled it and it said it cannot harm an unborn baby, but not to use it during breastfeeding because it can pass to the baby through the milk and may harm a nursing baby. But during pregnancy it is fine.
