I don't think it is 'normal'. I had the same happen to me at 30 weeks also, old brown looking blood and clots. Then at 32 weeks I had a bright red bleed and I ended up having my baby at 34+4. Phone your midwife because although I believe that you and bub are ok I really do think they need to know about this. Not saying you will have your bub early or anything, part reason for DS's early birth was because my bleeding didn't stop and my placenta was low.... and it was my decision (from Ob's advice) so am sure you will make the best decision for your own situation also. In my opinion you can't be too careful, good luck and yes you are on the home stretch now, yay!
