We have been trying to have another baby for about a month now and all of a sudden my husband has been acting very weird . Lately he has been very tired and not in the mood to have sex .and last night we where having sex when he stopped and told me he had to pee,then when he came back we started doing it again and he stopped and was like I'm sorry I'm just not feeling it today, then he went to the restroom and started throwing up,and he said that when he tried to pee it kind of burned . Should I be worried or could he have symptoms even before I get any??

There are those that say it has happened, but no there is no reason by science this would happen. It may well be his wishful hoping causing this.

Sounds like he is sick with something, maybe the flu or a uti.

This doesn't sound good. It burns when he pees? He's sick?

Time to see a doctor. Burning during urination, that's not a good thing.
