Question: I hope I am

Ok, so my last MP was on September 1,2014 and it has not come yet I am now 9days late and I WANT A BABY SO BAD!!! lol that I went and brought a Pregnancy test 2 days ago 3 of them 2 cheapies (btw, they were different brands) and 1 clear blue digital only to see all of them come back and say NEGATIVE... But I am still not convinced that I am not pregnant... Does anyone think that it was too soon when I tested? Could that have been the reason that I got a negative? I had 3 eptopic pregnancies 2 in the left tube which resulted in them taking it but leaving the ovary and I had 1 in the right which they had just cut out where the rupture occurred but I think it may have left scar tissue... I want this so bad I am 32 and this would be OUR first child together we have been married for 8yrs... Thanks in Advance for the comments I could really use the insight...
