I hope my last miscarriage didn't effect my efforts

Hello all! I am writing today (and promise to follow up to let you know what happens) because I am severly late on my usually normal period. I unfortunately miscarried on December 12, 2009...it was hard to get over. I have had pretty regular periods and My LMP was June 27, 2010. My boyfriend and I had sex almost everyday from July 3rd until the 14th...so being as though my ovulation was from the July 6th to 11th I am thinking we were successful. The only reason, or should I say reasons, I believe we were successful is because I have had most of the symptoms of early pregnancy. Missed Period (I am currently 9 days late), Tender Breasts (almost everyday all times of the day) Nausea (only for a few days) Fatigue (can hardly keep my eyes open, especially at work and when driving home) Frequent Urination, Headaches (every freaking day) Light Headedness ( only a few times) Constipation (Ugh), & Heartburn (everyday)...Normally the way I tell I am pregnant is the headaches and breast tenderness...I have two children and the last pregnancy that I lost confirmed that.
Heres my issue...these stupid hpts!!! I am one of those people who can test negative up until my 8th week :( I have taken about 5 tests so far, all negative...anyone else have a similar problem?

Referring to your subject title I asked my doctor the same thing and he said its only after you have 3 MC's that your chances are affected and only slightly after that

Both tests negative...ironically the period came while I was taking the test, weird...better luck next time...sure is fun trying :)
