Due tomorrow and

Hey ladies,

So I'm due tomorrow and haven't had too many labor signs but today I went for a massive walk and then had sex for an hour and ever since had lightening pain in my vagina and my belly tightens here and there (may be BH but no pain)

I feel like baby is going more further down in my pelvis. I also feel very gassy. Can't sleep. Anyone had any of this before labour? Or experiencing the same thing? Thanks
