Am I pregnant !! 😃

So I will start off saying I have been trying to conceive for the past 2 in half years . And I haven’t gotten pregnant I tried taking fertility pills that didn’t help then this past month in a half I started taking concieve plus and maybe a couple of days afterwards my period came so I’m thinking maybe their not working for me . But this month I haven’t came on my period and normally that’s not normal unless I’m pregnant and I have a 8yr old son, and my cycles are clockwork !! And I took a test on the the 20th It came back negative and I took a test on the 28th and it look like it could be positive I’m not sure I think I was staring at it too long lol but today would of been my last day on my period and I still haven’t started so I feel like I missed this month and I’m thinking about taking another test maybe I tested to soon . !! But I have been having headaches on going and normally if I take medicine it goes away but for some reason it’s been on going very light headaches and just feeling kinda weird too ...
