Need some Motivation Low HCG levels

Tara
I need to hear some success stories!!!
I had my <a href="https://glowing.com/glow-fertility-program">IUI</a> on 2/12
On 3/2 I had my first positive hpt and also had my beta done and my HCG level came back at 98
On 3/6 my second beta came back at 317 (I had some light spotting on 3/7)
On 3/9 my third test came back with a drop to 292.  We began to prepare for the worst and my doctor had me come in for another test on 3/13
Yesterday, 3/22 which put my at just about 6 weeks we actually saw a rise to 622!  Has anyone had a similar situation and have a healthy pregnancy? My doctor says it doesn't look good but there is still hope.  I am so trying to not get my hopes up but of course that's all I can do!
