I was on Microlut too, just two months after Faithy was born, and I felt really sick for about a month afterwards. It settled down and now, almost a year later, I am off it because hubby and I have decided we may try for another baby. The only thing is, I am waiting for my period to return so I can get in cycle.... so far nothing. Have been for three weeks, I know it said two months, but I'm a little worried.
Anyway, my hubby seems to think the best form of contraception is being pregnant.
