Not ovulating every month

Alex • I`m 32 and we are trying to conceive #2 now. Hopefully we will get our bfp soon 😊
I had blood tests that showed i didn't ovulate last month, does that mean there is something wrong or can that happen sometimes? They want to repeat the bloods. We have been trying for four months now and nothing yet. Hoping and praying for this month 😢 thanks in advance x
