My period has been so crazy .. some months it would be late then only 3 days long then other later and for a whole week long .. I don't get this at all..he only got his sperm tested once he was 4 months out they didn't say clear but just said the test looked good .. he was told to get it tested 3 months out a year out and they said it wouldn't hurt to get it tested every year after that .. but he has only that one time (4 months out)..
