Leyla - Both my SIL's (not related to each other) did not get +ve until they were 6 wks, and both had to get bts to confirm. So this can be normal

Jen - Hopefully it won't take a few cycles for you to get pg, but after a few cycles of temping you will get to see a pattern. One temp alone doesn't tell you much, it is a collective result that paints the pic. If you still don't think you are getting accurate results with temping orally then try "downstairs."
