Hi Sweetheart!
Are you really only 15 years old?
Do you have any support (ie: family/BF knows?)
It is normal and wish you all the best in getting the support you need.
most times in pregnancy you will experience that sort of discharge very early on..it is normal
So are you 15 years old and about 4 weeks pregnant? Or did you mean your 15 IN about 4 weeks?
