Light vaginal bleed with hard bowel movement

Hailey • 29 from Brisbane, having no. 2 (only 13 months after no. 1!)

So I'm not imagining things as this happened twice now. But like a lot of ppl in early pregnancy I've been fairly constipated and twice after a hard bowel movement I've had a light vaginal bleed that ends shortly afterwards and is light pink. Should I be worried?
