very light period but have had negative tests

Hi

over Christmas my partner and I decided to start trying for a baby so we have been having unprotected sex since 1st January. I was due for a period on the 6th Jan and it didn't start. On the 8th Jan i started what I then thought was my period but it was pink and then turned bright red but was very light, then the 2nd day was the same and was very light, I usually fill at least 5 super sized tampons and still leak on my 2nd day but I didn't even bleed enough to fill a tampon then on the 3rd day I stopped altogether.

I went to my local family planning clinic to discuss this as I knew it was not normal for me as I am usually on for 7 days and you could set your watch by my periods - at the time I was concerned there may be a problem.

The Nurse at the clinic advised me that there is a very good chance that I could be pregnant and did a test which came out negative, I have since done 2 tests which are still negative.

I have symptoms of pregnancy too - dizziness, nausea, bloating, backache, increased temperature but I don't know whether these are psychological because i'm thinking about it?!?

Could I be Pregnant? Is it too soon to test?

I was just wondering if there was anyone else out there who has experience a similar situation and what the outcome was.

Im kind of living in Limbo at the moment - back at the clinic on Thursday though to do another test so fingers crossed!
