2 negatives and stil im positive

I am due on my period in 2 days but since Thursday have been throwing up and not feeling myself. All of my symptoms are very similar to how I felt with my first pregnancy but Have taken 2 tests (1 normal and 1 for early detection) and both were negative... but I am still so sure I am pregnant... anybody else experience this?

**UPDATE** So AF was due tuesday and she didnt show... im am stupidly emotional (I cried because I wasn't hungry kinda emotional) and to top it off had a fall the other day so am suffering severe back pains. Keep getting weird feelings in my tummy, boobs don't fit in my bra and I can't buttom my jeans due to the ridiculous amount of gas I seem to have... sorry TMI

But still getting a negative test... If I am honest I am starting to worry as I had my coil out 4 weeks ago Tuesday and know the coil raises chances of ectopic pregnancy...

And although I don't think this is what it is my mind is playing some serious games with me... Anybody else having this issue or had this issue. Feels like im losing the plot lol
