Faint Positive Pregnancy Test

Over the last week or so this is what has been happening. On the 25th of January I got my IUI done. And Since then the same things has been happening like the last time ... tender breast (side effect from Ovidrel Shot) . However this time new things are happening. Breast are still tender after ovidrel is out of my system, and I have been feeling sick for days now, I never threw up but  i felt like I needed to. And also have I've been have light cramps for maybe 4 or 5 days now, but I'm not even spotting yet. I cant wait. For a while I thought... Ok my period is going to come really soon, and with my luck probably over the weekend. So I didn't really have high hopes at all.

The Ovidrel shot should now be out my system because I took a  Home Pregnancy test strip a couple of times a week and it was Negative. My nurse told me not to do anything until the 8th of Feb to take a pregnancy test. But me being me..  So I took a HPT (Home Pregnancy Test) tonight and this is what I saw.

The darkest line is the negative line and the one on the very top is just a part of the test strip.... But do you see the one in the middle (the faint one) ?

These are three test I took over the past 3 days. The one at the bottom was Taken today.

So I have about 4 more days to do before I can test for real. But since I've seen nothing but Negatives in the past few days ... This test is giving  me some hope.
