Does melatonin affect fertility when TTC?

I work nightshift and I typically require a supplement to fall asleep during the day. I’m concerned that using melatonin would alter my ovulation or just make my normal sleep/wake cycles out of sync(even tho I deal with insomnia and irregular sleep-wake cycles from nightshift already). So I’m finding myself worrying about little things I usually wouldn’t make a big deal about. Like oh what if this prevents me from getting pregnant when I could just be paranoid.
