Jenae • I`m 24 and I have a daughter who was born 3/23/17 and son born 1/30/22!!
I went to the doctor last week at 4 weeks exact and my hcg levels were 632 and they said I was around 6 weeks, instead of 4.  So I asked if I'm around 7 weeks now and she said yes. So I'm wondering what I am.. I'm so confused?? I can't wait for my appointment on August 5th!! So I can know how far along I really am!
