Should I be worried? Tmi about husband's sperm amount..

So at the moment were not trying super hard to have a baby, but were not- not trying. We just don't want to stress out. But this morning I gave my husband a handjob and his cum looked like there was a smaller amount than usual...but it's been a while since I gave a handjob so I'm not too sure. Should I be worried that there's such a small amount or try again later n see if it was just the Time of day since I'm pretty sure he plays at night with himself...lol. Sorry for such tmi.
