Yes or no? I've had 1 positive and then about 4 tests after negative? Is this test negative as well?

Kaela • I`m a 21 year old woman who is now trying to have a baby! I have to take clomid to help me ovulate due to Endometriosis and irregular cycles. Hope it helps! (Just started it)
Here's 2 pictures, one original and one negative. I've had 1 positive test last week, waited a few days and took another and BFN. Doesn't make sense to me ? also, my obgyn was able to squeeze milk out of my breasts?! And I'm overly bloated with headaches and nausea. Can someone please help or advise?
