Effects of RF Microneedling While Pregnant?

I had 3 sessions of RF microneedling done 2 years ago. My final session I found out I was pregnant the day before (4 weeks pregnant). Esthetician said there was no problem at all with that and did the RF MN. After I had my baby I noticed my face is way different. Long, thin, saggy. I’m confident RF microneedling caused fat loss in my face. Did me being 4 weeks pregnant contribute to this? I only gained 23 lbs my whole pregnancy. Is there anything to do to help? I’m 35
