First Round of Letrozole

Laying in bed doing my best not to symptom spot. But been having some cramping today and now having sharp pinching like cramps on my right side. Also I have cried over stupid disagreements two days straight now. 10 DPO and doing my best to get through this TWW without testing. I was doing so well (not testing) before I started any meds, but now I am so anxious on the meds. Any words of advice or encouragement??
