It's quite common to spot pink blood around this time. Don't worry too much but if it continues maybe pop & see your GP to put your mind at rest.
If it helps, with all of my pregnancies I've had pink spotting up until 14-16 weeks.
Take care & try not to worry x
Ive been told thats normal!!! call your OB ive always been told pink and brown are good bright red is the bad one. hope everything is ok!!!
