A sign or just wishful thinking?

I’m 36 weeks pregnant and for the past few days I’ve woken in the night with very mild period cramps, similar to what you get when your period is due in the next few days. I’ve also been feeling sick at random points throughout the day, had an upset stomach, and pretty much constant Braxton hicks during the day.

Is this a positive sign, or all just a weird coincidence? 🤷🏻‍♀️ I’m a FTM in case that much wasn’t blindly obvious 😂
