Dates??

Ka

So I’m not sure of my last AF because I had a chemical pregnancy last cycle so my “AF” dates are thrown off. I do know I got peak LH surge on 5/12 which would mean I probably ovulated 5/13. My blood test I took on 5/28 showed HCG 162 which the nurse showed about 4 weeks pregnant. Those dates would add up about right...right??
