Labor approaching?

Labor approaching? Or wishful thinking? 😵‍💫 I am 38 weeks pregnant. I just started to experience period pains with mild cramping and lower back pain. I’ve been nauseous today on top of the fact that I just don’t feel like myself. I don’t feel well, and I don’t know how to explain it. I have a headache that has come and gone a few times but I checked my blood pressure and it’s fine. I also have felt like I need to go 💩 a few times today but I don’t actually have to… I’m also so tired, took 2 naps today and my appetite isn’t existent today. And of course BH that have been throughout the day. I’m sure tomorrow will be better but todays symptoms alone have me questioning things. Thoughts? FTM so I’m just lost 🤷🏼‍♀️
