5 weeks today

Feel like my cramping has gone away unless I lay down then it feels kinda tight when I breathe in my abdomin and some cramping feeling down my vagina. Normal ? I'm on progesterone and when it's low I seem to cramp more but it was raising so think maybe that could be why im not as crampy? Worried things aren't progressing I have blood work again tomorrow as this last wendsday hcg was at 384
