if your OBGYN was aware of it and didnt feel concerned then you and your baby should be just fine! also if you had a normal u/s done then everything is 99% ok!!!!

after the first trimester the chances of missacrriage decrease tremendously

is that like a nasal spray or something? im not sure. my dr when taking zyrtec and such told me to stop in the first trimester but once i reached the 2nd trimester i could resume taking it, you can always double check with your dr if you feel you need it that bad. Class A drugs are the safest, class C they will not give you when pregnant unless the risk towards the baby is low compared to the risk of you not taking it, i think that makes sense lol . i was trying to write it so it makes sense not sure if that came out right.
