Not sure if I could be pregnant

Hi, I'm 29 yrs. old and my husband and I have been TTC for 7 months now.  I came off birth control last October after 11 yrs. on them.  I have also been charting my menstrual cycle since October.  I ovulated on Aug. 8th, I had egg white cervical mucus and we did the deed on 8th & 9th.  I was due for my period on Aug. 21.  I'm 23-24 days cycle.  Well, Mon. came and no period so on Wed. I decided to take First Response test that evening and it was negative.  By Friday my nerves were needless to say a little shot so I decided to take another First Response test that afternoon and it was negative.  Now its Sat. with no period.  I don't really have any symptoms other than I feel like I'm leaking so I run to the bathroom and nothings there, boobs feel fuller and they are a little sore but that has been on and off, lower back as been hurting on and off since yesterday, today I noticed blue veins on my boobs and chest area and sometimes they are more noticeable than at other times, don't really feel tired and a couple of times I felt queasy but that only last for a few minutes, have been cramping slightly but don't need Advil for it, feel bloated.  I have never been late before especially like this.  Is there any chance that I could be pregnant eventhough I took 2 test that showed negative?  Or does that pretty much say that I'm not pregnant? With the 2 test I never took them using first morning urine either.  Should I call my OB/GYN dr. next week to get a blood test, if so, how long should I wait? Can you be pregnant with no symptoms? Sorry for being so long,just confused. Thk

test with first morning urine, it is best.

Try another brand of test also - some are much more sensitive than others.  I buy the store brand CVS ones and find them the most sensitve - I've had positives on those 2 days early when brand names (I think first response was one) showed negative 1 day early.  Based on your symptoms, sounds like you have a good chance of being pg - good luck and lots of baby dust to you!

I took 8 First Response Test all where BFN so the same day I said I am pregnant I know it.... I went to Doctor got a blood test came back BFP..... So I said why didn't the First Responce pick it up. I did a test I went to Wal Mart and got 6 brands including the Digital and First Responce. All test gave me good BFP but the First Responce still gave me a BFN Take different test :)
