Constipation & Pregnancy


Just wondering if constipation is an early sign of pregnancy? I am supposed to start AF today, but have only seen light pink spotting. I'm pretty regular with going #2 so this is kinda off for me. Also I have really tender boobs, but it's also a period symptom.....and normally I get diarrhea with my period. What's been your experience?

Side note: we've been trying almost 2 years
