Baby kicking super low?

I'm 17+3 with baby #2 and we started to feel definite kicks/thumps this last Friday, but they are suuuuper low, right below my hairline. I'm also feeling a lot of heavy pressure down low... I don't remember this with my son. Anyone else feeling like baby is hanging out super low? Just curious!

P.S. Funny story... took my 6 year old to the movies on Sunday and baby started thumping like crazy once the previews started... wondering if the loud theater made him start kicking!
