IUI & Clomid-advice...comfort?

Hi ladies.  I'm driving myself 100% crazy so, I'm posting this in hopes someone has had a similar experience? This month my husband and I did our first round of clomid & IUI after ttc naturally for 2.5 years.  2 days ago, I couldn't believe my eyes when I saw my first faint line EVER!! I continued to test like an insane person- still getting faint positives. Fast forward to my first blood test. HCG 15. Rutt-Roh. I take my second blood test tomorrow. My hpts aren't getting darker. Rather, staying the same. Scared out of my mind it will be a chemical. Trying not to get excited but also, I'm actually pregnant for the time being!
