ok so my last period was from the 1st to the 4th (my cycle is 30 days)and i had sex on the 17th...i went to the doc on the 28th and had a blood test done(it was qualitative)and it came back negative but that same day i started experiencing dark brown spotting (my doc said it was old blood)and it last until yesterday the 31st. I never had that before so i started researching it and i though it might be implantation bleeding...if so wouldnt it have been too early to do the blood test? I really feel as if i am pregnant ive been having mild headaches, been feeling sick during the morning and at night but i dont throw up,oh and i have to use the bathroom alot to pee but then i feel constipated(sorry tmi),and i also feel warm all the time so when i check my regular temp its like 98.6-99.5,i can smell every single little thing...even when someone comes out the shower i can smell the soap as if they were sticking my nose it it,and i am SOOOOO tired today i woke up at 12 ate at 1 slept till 5 ate some more fell asleep woke up at 7 ate and fell back asleep now im up and im hungry,but one thing that bothers me is my whole body is really sore especially my hands and feet and this has NEVER happened to me before(i was wondering if anyone else has experienced that in early pregnancy)...so unconvinced i took a early response preg test today and its negative but af has not come yet...do you think i can still be pregnant?(sorry its so long)

well tommorrow i find out the results of the blood test

If I'm understanding this right, you're already 3 days late...if you started on 1st and your cycle is 30 days you should have started again end of March, and you haven't. The timing of having sex sounds about right and the symptoms definately sound right for pregnancy - maybe wait another day or two and try another brand of test? Good luck!
