Threatened M/C

Leigh

So after having a m/c in Aug last im now 6 weeks pregnant with my rainbow baby. I began spotting 6 days ago and of course thought the worst but as it was more brown in colour and mainly when i wipe (also with cramps off and on) doc said he thinks could be threatened m/c.

Have any ladies had this before? If so how long should it last and if m/c is likey to occur how soon after should it happen?
