回複：[用排卵試紙的姐妹們幫我看看] 試紙測不到排卵

it could be due to several possibilities:

1. Ovulation happens between 2 test strips, so none of them show positive result.

2. Test strips are expired.

3. You havn't ovulate yet. It could happen on 19th to 21st day..

4. You don't ovulate this month. It could happen that you don't ovulate every month. 

所有跟帖： 

• 是不是不能用晨尿？我以為晨尿濃度最高，但是今天聽說，一般不用晨尿測排卵 -阿朱朱- ♀ (0 bytes) () 08/07/2012 postreply 13:58:58
