Yes, absolutely. Not to mention other issues that only present themselves during pregnancy, like heart problems, breathing issues, even diabetes.
Fainting is pretty rare, though more women can "feel faint" instead Think dizziness or head rush. Lots of pregnant women have that. But full-on fainting is often used as an indicator of pregnancy. There's even a blurb about it on tvtropes.
But unless Sakrua's come down with Itachi's mystery illness, I would say there has to be a reason for her to be fainting...and more importantly for the other characters to be making note of it. Shizune addresses it calmly, and Sarada certainly isn't at all freaked out.
Honestly, I'll be disappointed if it all comes to nothing. They sideline Sakura with a mysterious fainting spell that suddenly remedies itself in 8 chapters. Long enough for her to be a plot device then conveniently excuses herself from the story. Even if it's not a pregnancy, I hope it turns out to be something!! Not just a way to get her out of the picture!!
edit: @shadow /\ lolololol at your post!
I wouldn't be surprised if it was nothing. Think back to 693 (cringe) might as well have told her to get back in the kitchen. I still can't believe that they didn't have Sakura play any sort of part in a fight between Sasuke and Naruto.
