I'm so confused!!

Chanel
Hello all!! I'm 42 years old and have been trying to conceive for 6 months now. In October my period was very abnormal, mostly spotting. This month my period is 10 days late. Took a pregnancy test last week and it was negative. I've had no pregnancy symptoms other than fatigue and I'm very emotional. I'm not sure what to do or think at this point..any suggestions?!!
