ovulation after birth control pill

Megan

Has anyone ovulated late right after coming off of birth control? I missed my period 8/26 and got my positive that day as well. I went and got blood work yesterday but my hcg is only at 89 which my doctor said is about 2-3 weeks. And this morning I had brown light spotting. She doesn't seem worried but it seems low to me.. Anyone else have something similar? Trying not to feel anxious..
