Normal?

This is my 5th pregnancy and 4th baby. (We lost one)

With my first I had ZERO signs of pregnancy, no nausea, heartburn, sore boobs, nothing...

The next two were horrendous, puking till 14 weeks, constant headaches, sleeping literally any chance I got..

Now this time I'm guessing I'm about 4w1d and I feel nothing but being sleepy, occasionally nauseous, no vomiting though, and minor headaches.

Anyone have the same experience, and just not have many symptoms? I'm not missing the sickness but I'm just worried something may actually be wrong. 😬
