2 LH surges?

Holly

2 days ago, during my first pee of the morning I tested and got a negative but it was very very close to positive. A couple hours later I tested again and got a positive, same color as the control line. My husband and I BD’d and I was so happy to have a positive. The next morning (yesterday) the test color had faded to lighter than the control line, so I and Glow assumed that I had ovulated the night before and the surge was already over, but my husband and I BD’d again for good measure. Now this morning, I tested again with first mornings pee and I have a positive that’s even darker than the test line!! Can first morning urine cause a false positive from LH stored in the urine overnight or is something crazy going on?? I’m planning to test again in a couple of hours to see what I get, since I’ve found in past cycles to get the most accuracy on the second pee of the morning. I hate to sound so neurotic but I miscarried on my first pregnancy and after waiting for a first normal cycle to pass we are now trying again.
