If it were late in flowering and raining for many days you might have reasons to worry. But since its early flowering she should be fine. You could always cover her from the rain though as it can be known to have contaminates in it that can cause mildew etc. But if its just a couple days and then sunny again she'll be ok. My 3 girls endured 2 weeks of on off rain in the spring and i was freaking out, but they did great handling it, the wind caused more damage than any rain.
Happy flowering season 😊
