Growth spurt

Rachelle • Mother to 3 daughters and 3 sons. Mother to 3 angels taken early in pregnancy. Currently pregnant with my number 7.
So I'm 17+4 weeks pregnant. And since becoming 17 weeks I've been it with a really big over tired phase. Like literally sleeping all day and all night. Woke this morning and I think my bump has gotten bigger. Could baby and my body have had a growth spurt causing me to be super tired??
