Is it too early???

It’s only been 6 DPO but I’ve woke up nauseated the past two mornings - and I’m feeling way tired. Could this be early pregnancy symptoms already or am I crazy?!? Lol.

My last two pregnancies, the first one was successful, but I miscarried my second in May, I had the same symptoms but never this early I don’t think.

The fertilized egg (if fertilized) shouldn’t even be implanted yet! Lol

Anyone experience anything similar before?
