Stress or pregnant?

Shanie

I've been temping for a few months now. I typically have around a 35 day cycle. I'm on day 46. I took a few pregnancy tests last week, all negative. However, my temps this week are high! And they aren't going down. To make things more complicated, my father died last month so for a week, my sleep was all messed up and I was stressed out, so I'm missing about 2 weeks of temps.

Any idea what this could be?
