My period was supposed to start Monday, and it is now 4 days late. I took three tests, the first didn’t show, the control window never showed up. The second two were negative, but I took in the afternoon/ night both times.

I don’t feel like my period is coming.

I have to pee 1-2 times an hour, and was extremely tired last week and threw up clear liquid once last Friday morning (3 days before expected period).

But don’t seem to have any other symptoms. Not sure if I should just keep waiting or buy a more expensive pregnancy test and test in the morning ?
