First month without Clomid, TTC naturally and no PMS symptoms

From Sept. - Dec. I had 3 IUIs and 4 months of Clomid (one unmonitored cycle). No success. This has been the 1st month since August that we've TTC naturally and its CD 26 and no PMS symptoms but negative test result yesterday. Has anyone else missed symptoms/AF in 1st month Clomid-free - but not been pregnant? Trying not to get my hopes up since we've been trying over 2 yrs!!
