Hello everyone! Girls, could you please tell me, I'm 23 weeks pregnant…

Hello everyone! Girls, could you please tell me, I'm 23 weeks pregnant and my allergy started earlier. Before pregnancy, I had allergies to dust and chemicals, almost 6 months I didn't suffer from this. Yesterday I took Tavigen, it was very bad for me until I couldn't reach my doctor even today in the afternoon my active baby started moving slower, how can I be now and is it possible to cure it with natural remedies? Has anyone else experienced this?
