Feeling slight pains

Trish
I am 31 weeks and have this slight period like pains in belly and below till legs. My back was terrible two days back and I chose to work from home today. I have been really stressed as my dad is in icu and I cannot meet him. Can this pain be any sign ? I have it constantly , baby is moving normally . I have two more months to go and I did read that people have false labor. Don't want to simply panic but still wants to know if anyone knows what could this be
