bleeding then spotting in early pregnancy

hey everyone,

I am 5 weeks and three days pregnant, wen i was 4 weeks 2 days i had bright red bleeding which came without any pain (just a lile tired feeling in my thighs) then there was nothing all night. next morning i had dark brown spotting which got heavier. but no enough to soak a pad,,i wasnt worried because i had a miscarriage in july and it started as dark brown discharge. i got my HCGs tested and they r rising with a good rate.. 12000 on first test and 17000 on the second.. dcotor was ok with them. i am planing to go for a scan but its too early as i wont see anything there. then the spotting got really light .. i have very light brown discharge but wen i took a shower i got two spots of fresh blood again so i lied down with pillows under my feet.im taking it easy. my mothe in law asks me to rest but i feel baby is gone already coz of my previous experience (alhtough i soo wish i dnt loose this baby) HCG levels gave me some hope. this is my second pregnancy (first one being a miscarriage) after trying for 7 years.. i have pcos which has gone better with good diet n exercise. i would like to know wa others went through. has one went on to have a normal pregnancy with bleeding or spotting during early pregnancy?
