Ideal CM and window to have sex

Daina
I just checked and I have the ideal CM consistency (I didn't have this at all last month). I won't see my husband tonight until about 7:30. Is there a small window that this consistency lasts or should I be ok until 7:30 tonight? Lol I feel like a crazy woman and want to leave work and scoop up my husband real quick for a quickie LOL. Any advice would be great! Thanks
