Is it the test stick or am I really??

Hi ladies I purchased the most affordable test stick at Walgreens and the first test was from this past Wednesday, the second test was today. Why is the control line sooo light? Am I really pregnant? Has this happen to any of you? With my first two children the control line wasn’t this light! I’m going to go purchase a few more today just to test again and make sure. This will be my third baby and I have a 7 month old currently via Csection so I’m def panicking a little! Ahhh
