HELP!

Ok ladies so I had my period January 5-9 and then I ovulated January 26-27th. A couple days after I ovulated I started to get super tired and and on February 2nd I felt so nauseous all day after work I ended up deciding to go lay down and my husband came up like 30 minutes later and i instantly sat up and knew I was gonna throw up he gave me the trash and I puked about 3-4 times and then I felt normal literally like nothing had happened. I didn’t have a fever and then the next day I was nauseous too. So I was like crap maybe I’m getting sick. I kept track of my temp after that for the next couple days and I never got a high temp everything was normal. And I waited for my period. Well my period was suppose to start February 8th and nothing. none of the symptoms I usually get before my period.

I feel perfectly normal. So I took a test about 3 days after missed period and BFN and now I am on day 20DPO and I’m a week late and nothing. Anyone have any ideas? Am I still in this or am I outta luck? Called my doctor and he doesn’t wants me to wait a week!
