Good day ladies! Yesterday I started bleeding, without blood, light mucus. Yesterday everything was normal. Today from the morning it pulls my belly, and there were pink discharge, but already creamy. Called the doctor, she said to observe the frequency of pain and be ready. But there is no such periodicity, he just always pulls. Especially when I move. So I lay down and lie down. The discharge in small amounts remains as it is. The baby moves as always. Has anyone encountered this? Is it starting? I'm worried
