How likely is it that I'm pregnant? I am having irregular periods but I started getting a 39 day cycle before this was between 25- 28 days. I usually get bad pms but nothing this month. I am a day late now I am starting to feel a bit sick, I have been having a lot of gas and I'm sleeping a lot. I've started getting cramps but still nothing I took a test yesterday and a test today with fmu and negative results. What are the chances I'm actually pregnant?
