Help!

Rebecca • 40 and hoping to get pregnant with baby number 2 in the next year!
Hey ladies-
​Got my BFP the other day; took a different test today and got a BFN. A little bit freaked out here. Is it because I didn't use first morning urine just now? Could it be a false-negative? Trying not to think of the alternative. 
​Also, have another test to use in the morning. Should I take it tomorrow or wait?
​Thanks! 
​I posted this originally on the TTC board and then read that I'm not supposed to post any BFP news/questions there. Sorry!
