Allergies are killing me!!

Janelle • I`m 30 I have a daughter that is 6 and considering another since being divorced and being a single mom I now I met a man that loves me and my daughter dearly so he has no kids so looks like maybe soon
I'm 19 weeks with our baby boy💙 have been struggling with allergies last 2 days what is safe to take? What has everyone tried? I have never had allergies before so it's all new to me. Thought it was a cold at first. Help!!!
