Symptoms at 36 weeks

Baby was 3/5 engaged last week and had a growth scan this morning but they couldn’t measure the head as she’s so far down.

Anxious that she might come early and I don’t feel ready yet! These are my symptoms:

-Indigestion & nausea returned;

-Upset stomach for the last week;

-Dull lower back pain;

-Stomach tightenings (painless) half a dozen times a day for the last three weeks or so;

-Mild period cramps;

-Aches in top of thighs;

-Increased discharge (almost like water?)

Anyone going through the same? Does this sound like baby is almost ready?
