Light pink blood while trying to poop?

TMI:

Hello everyone. I’m 3 months pregnant & I’ve been severely constipated for the past two months! Doctor prescribed me Colice soft gels, which doesn’t seem to work. I’ve had probably a hand few of bowel movements that are which very small balls. I’m afraid to strain because of baby. But everytime I seen to have a bowel movement, I notice when I get up a small amount of light blood in the toilet. And this only happens when I try to poop. Mind you, I don’t strain at all! It’s just when the poop try’s to come out and I have a small movement, this happens. And I wiped to see where it’s coming from, and it’s coming from my vagina.. Have this ever happened to anyone and everything was ok? I just called her and she recommended me to start taking Miralax. Have anyone took this and knows that it will definitely help and not harm the baby? I will attach photo.
