Hi everyone, just wondering if any one can give me some sort of answer or insight to what is going on!

My last period was on 16th December 08 and its now 18th feb 09 and i haven't had a period in between. I have taken 3 pregnancy tests 2 supermarket brand and one clear blue , supermarket tests were taken 1 week apart then i left it 2 weeks before i took a clear blue one which was taken yesterday 17th feb 09 all 3 tests were negative.
Obviously i don't think i have taken the tests to soon as its been 9 weeks since my last period.
The only symptoms i have are sore breasts which have been consistantly sore for the past 5/6 weeks and possibly being tired which i think is my own fault as i have a distruted sleep pattern due to uni and work.
I havent gained any weight and i dont use the toilet any more then normal.
I have had two out breaks of cold sores one the 26/12/08 then the other 15/2/09 ( though im not sure this has any thing to do with this).

I am sexually active and do have sex regularly a few times a week but we don't use protection ( i know i know) reason being is he cant actually produce any thing when he orgasm but never the less he never does orgasm in side me.

Additional details : Im 20 years old, about 5ft2 and 196 lbs (yes i know im overweight)

What do you think could be causing this? Do you think i could actually be pregnant despite 3 negative tests?


Please do not tell me to go to the doctors as when i have previously wether related to periods or other things they tell me to go home and sit it out or loose weight!
