Second (plus) time mom question

Christin

So I’m pregnant with baby #2, but my son is 2.5 years old so it’s been a minute… I’m like 13DPO (actually 8dp5dt since we did IVF) and my nipples already seem to be darkening and the boob veins are so prominent. I don’t remember this happening until like middle/end of first trimester last time. Plus I’m already so tired. Anyone else having faster symptoms than their previous pregnancies?
