Hi, I have 5 children..and have varying degrees of seperation and bleeding in each pregnancy..The longest I had to wait for it to heal was between 17-20 weeks, the others have all been fine by 12-14 weeks..but it is very stressful to always see blood when you go to the toilet and it is easy to become obsessed with checking.
I highly recommend, rest!!! feet up higher than your tummy, and talk to your baby..
definbatley no sex..in the scheme of things it is'nt a long time, most hems resolve themselves by 12weeks ish end of the 1st trimester..wishing you the best of luck!!!
