IVF Stim Side Effects - Please help me calm down

Hi all, I am on my fourth day of taking Puregon (follitropin beta + estrogen, aka same as Gonal-F) and I am starting to have some emotional and physical symptoms. Mainly increased anxiety, being in a funk, brain fog, some bloating, upset tummy, and some dizziness. I spoke to my pharmacist and he said it was normal, but it still scares me that it's something more serious. I have written to my doctor but of course it is Christmas. I feel sort of restless but also more sensitive and irritable. Any advice or encouragement or similar experiences would really help me !
