I had miscarriage on jan 2017 now I missed my periods for 6 days and I took beta hcg. My beta hcg level is 253. My last periods date is may 7th. When I coulsted a doctor she said that level is low and asked me repeat the test. Im worried to the core that I may end up like last time. Kindly tell me is it very low and also I get slight pain like a periods pains but its just a slight pain. Kindly let me know if it is not a good symptom.
