当门铃响时我碰巧在洗澡怎么翻译

I happened to be bathing when the doorbell rang.

The door bell is ringing when i washing my body.

Right the doorbell rung,i was taking a shower.

I was bathing when the doorbell rang.
1\2\4楼，同时用进行时表示一种持续的状态，不能用于表示“正在做某事的时候突然发生了另外一件事”。
3楼，我好像记得happen to 后面是直接加动词原形吧？

When i was bathing the doorbell is ringing
