Spermicidal Lube. Is it okay to use until my period starts?

I don't have an answer for the spermicidal lube, although I recall it should contain nonoxyl nine, but, you can't get a positive pregnancy test until 2 weeks after you should have gotten your period. Maybe as fast as 10 days, but that's the soonest. It measures a hormone and it has to get up to a measurable level to show up. Hope this helps some. Good luck!
