Question
My wife is pregnant am I allowed to still have sex with her and is there any time limit.
Answer
This is a matter of Physical health. If she is healthy, then there is no harm. However if she is sick and frail, then you should have some consideration for her and control yourself. Rasulullah sallallahu alayhi wasallam would abstain when an ummul mu’mineen would have a fever or headache.
