Got my blood work done on Tues Nov 22nd and it came back back 33, had it done again Fri Nov 25 and was 163. The doctor said both of these are low ? My lmp was Oct 26 and Ovulated Nov 10-12 roughly ... I also wiped last night and had light pink blood but not a lot just a little and only when I wiped once. are these numbers bad ? I am only about 4 weeks ? Should I be worried !? Ladies help me
