Advice over ovulation

I think I've possibly ovulated twice I've had egg white cm twice this month and am 2weeks late on my period but have egg white cm and all ovulation signs. My question is, is it possible to ovulate twice and not come on your period? Just skip it. This is very unusual for me as always on my period like clock work but all tests have come up negative for pregnancy and now I seem to be ovulating again. Thanks in advance x
