IDK IF IM PREGNANT please I need feedback

So I'm 20 years old I want a baby so bad and I believe me and my fiancé are ready. 
    So here's the back story when I was 18 I found out I had a heart shaped uterus and was told it may be a little more difficult to conceive. Well me and my fiancé have been trying for 5 months and every month my period came. Well this month is a little different I was supposed to have my period on the 12th she's still a no show I have VERY light spotting barely pink and I have a few other pregnancy symptoms but I don't want to get myself over excited because I've taken TWO tests and both came back negative my doctor is having me come In for blood work to check because of my condition Hcg may not be traceable in my pee but my question is with all my symptoms a week late period spotting very mild cramps tender nipples peeing all the time and I've gone number two 2 times a day now for 1 week plus I keep getting these horrible headaches there are these GIANT veins on my breast that were never this visible before I can't stand the smell of my apartment which I've been told doesn't have a smell last night my fiancé bought me fried rice and it made me gag (I LOVE FRIED RICE) so idk I guess I'm just looking for some feed back from you lovely ladies
Thanks
