Welcome to HCM.
First of all congratulations on conceiving.
By LMP you are 13 Weeks 3 days pregnant as of today. Since you had bleeding, it is advisable that you consult your obstetrician and get an ultrasound
scan done to confirm that every thing is alright.
Drink plenty of fluids, as hard stools result in straining to pass stools which in turn could cause bleeding from vagina.
Adequate fluid intake with fresh fruits will loosen the stools thus avoiding straining to have bowel movement.
In all likely hood every thing should be fine.
Wish you and your child growing in your womb all the best.
