Could it be stress, my pcos or am I pregnant?

Claudia
Hello ladies I need some advice!
I started taking provera in July for 3 months due to my pcos and my doctor wanted for me to have regular periods so for 5 months I  had regular periods but in December and and this past month I haven't gotten it. I didn't think much but then I started feeling cramps, bloating, and nausea. The other day someone just walked near me with the smell of downy on their clothes and I wanted to throw up! I took a couple tests as the days have gone by only to see a BFN
Everyone is saying I'm thinking to much in to it. 🙁 but I feel like that's not it all. Has this happen to anyone that can fill me in on their experience.
