Thanks for your comment, the discharge stopped after 2 days so very pleased! Got a Doctors appointment tomorrow but I think I'am now nearly 6 weeks, will keep you posted!
I'm 4w5d prego and I've been having short/minor cramps since day of conception, also I had brown/pinksish discharge at 3w4d and so far my beta numbers look very good. So, donot stress it is implantation bleeding. Good luck and keep taking care of yourself!
i had this when i was pregnant. if its brown it could be old blood and nothing to worry about :)
if you do get cramps and start bleeding go to hosp.
