Preschool refusal

Recently after my 2 year old daughter fell sick and had 1 week mc, it has been very difficult for me to get her back into routine. It has always been a challenge to persuade her to go to school but even more so now. She refuses to go to school and throws a tantrum and refuses to wear her uniform. She tells me please don’t leave her and to go to school with her. She will cry at drop off but at the end of the day the teachers tell me that she was played well and enjoyed herself. Any tips to make my mornings better?
