Dear Kristen,
Your symptoms look to be overlapping. Lets start with your first episode of reactions you experienced with clomid. Your
shortness of breath,palpitations point out to an
allergic reaction. If you have confirmed this reaction to clomid you need to take caution if ever you need to repeat the drug.
The symptoms of
frequent urination is normally experienced in pregnancy and will definetly ease away once you have delivered.
Abdominal pain is still persists, suggest that you inform your doctor as this will be further evaluated.
Take Care and A Safe Delivery.
