TTC (soon) and allergy immunizations

Amanda • 💕👶🏻🎀
Our original TTC start date was April 19, but now is pushed back to June 6 and I'm devastated. I have 16 more doses (so 8 weeks - since I have to go twice a week right now) left before I am to the maintenance vial and go down to twice a month. My DR recommended that we do not start TTC until I reach maintenance level.. I was just curious if anyone here has gone through allergy immunizations during pregnancy or had any insight?
