Hello everyone. Girls, could you please tell me?

Hello everyone. Girls, could you please tell me? The second pregnancy is 12 weeks and 4 days. There's no cramping at all. It feels like I'm not even pregnant. ?. Before that, I felt something, now there's nothing. I had my first ultrasound, they said everything was fine. The doctor prescribed Terzhin candles, how do they affect the baby, are they harmful? Something makes me worry. Thank you in advance.
