:'( on january 16th I found out I was 4 weeks pregnant I had a lil spotting an I went to the er because I was scared... this is my first pregnancy so the doctor took my hcg level it was 218... I went back 2 days later and it shot up to 722..... last night I went back 2 the er because I was spotting again an my hcg level went back down to 490..... is it normal for your hcg level to go up and down at 4 weeks?
