Chemical pregnancy...doctor's comment

So this has been bothering me..so a little background on me.

I'm 21 with some uncommon health issues. I have had multiple ultrasounds with everything reproductive being normal. Trying since July.

Well I have had at least 2 chemical pregnancies with one confirmed. Both were just before 5 weeks pregnant.

I had a follow up for the last one and my ob/gyn told me its not a pregnancy till 5 weeks so she can't do anything till we hit the year mark in July. So according to her I have never been pregnant.

I'm disturbed by this and upset that at 21 conceiving is proving very emotionally and physically draining!
