Are you congested too or you just get migraines? The reason I ask is because I don’t think allergies alone can cause a migraine but sinus congestion can cause a migraine. If it’s just headaches and no congestion, sneezing etc., I would guess that the migraines are pregnancy related and have nothing to do with the cat. I had really bad migraines in my second trimester.

I think it’s definitely possible. I have found the opposite though – things I was allergic to before I am not anymore. I never could drink milk without severe stomach issues, I can since I’ve gotten pregnant. I also used to be allergic to apples – they would make me super itchy, but now I can eat them without problems (good thing too because I am currently obsessed with them!)

I think you would have taken longer to show symptoms if it was the cat. Her dander wouldn’t suddenly explode in our house the moment she came home. Have you had you blood pressure and blood sugar checked lately? It could also be your sinuses. When you move your head around does it increase the pain? If so call your dr and ask what you can take for it and see if it helps, otherwise I’d consider making an appt. to make sure everything is ok. Daily migraines arent normal even for allegy sufferers. If all else fails Ad you think it is the cat you can take plenty of OTC allergy pills. Again double check with dr, but I was cleared to take Zyrtec, Claritin, or Benadryl.

After 29 years if eating shellfish, my mom became allergic while pregnant with me and still is to this day!!!  Crazy.
