Hi ! I m 21 weeks pregnant I had a clot 2 months back between uterus and placenta on 21 April ultrasound. I was on bed rest from then thereafter I had to be hospitalized on 1 may due to heavy bleeding n then on 10 may also for same. After this I took bed rest to the leg end elevation n my problem of bleeding resolved. Now after 2 months i. e. yesterday I was having brown discharge on time of passing urine I.e. even of 2 inch size. Till now this is happening. I had ultrasound yesterday that showed baby is fine but water level is 7 that was 4.5 last week n I have been taking water approx 4 Ltr. , juice,  coconut water n milk etc.

pls. suggest me reason of thick brown clots.
