I'm 8 weeks and 4 days (according to the ultrasound, I'm a week ahead), and today I started to feel some "stretching" on my stomach. I read that it may be called, "ligament stretching". It feels as if the whole lower belly is tight, light but noticeable- maybe like someone took a pencil point and drew a smile across my lower belly. Not really pain, but it really feels as if it's stretching. Is this normal? I didn't drink as much water today, maybe it's bc of my diet?
