So I'm a ftm and just barely at 14 weeks. Today I've been having absolutely terrible lower back pain, almost like muscle spasms. So it's been more difficult to bend to pick things up or sit/lay down. When I'm still I don't hurt. And I took some Tylenol which helped a bit. But I'm just wondering, is this normal with my center of gravity shifting? Did I lift something too heavy? Or should I be worried about something worse? /: Thanks for your responses/help
