just got my period back

My hubby and I just started TTC our 1st. I just got my period back after not having since October (when I stopped bc). I'll b 30 in July we had to wait because I had a brain tumor removed and a pituitary resection 4 years ago (I opted for intense follow up not chemo or radiation because they weren't sure if the tumor was malignant or benign due to Ucla losing my samples) my question is since this is my first time having a non BC periods since 15y/o I'm having a hard time with my emotions and eating and to make it worse I'm a NightShift RN. Any other nightshift people out there? How do y'all manage stress, and fluctuating hormones (mine are on overdrive) when TTC?
