I'm 13 weeks pregnant and before pregnancy had a very mild cat allergy which didn't generally bother me unless I let cats right near my face (I have 3) since being pregnant my allergy has gone NUTS, I'm awake gasping for air in the night because I can't breathe through my nose so it keeps my awake, then the second I move in the night to go the loo it rubs like a tap so u can't get back asleep! My heads permanently pounding too, is there anything at all I can take that's safe in pregnancy? I know this will pass because this is my fourth pregnancy (previously all losses) and when the pregnancy ends so does the allergy so rejoining isn't an option, I just need a safe remedy please??
