Feeling a little hopeful, and discouraged.?

i have got a negative 3 days past when my period was supposed to start....after a week went by i still had no period and i test and the line showed up slowly....then by the following week i tested again and it appeard....dont worry try not to stress over it i know its hard not to but you have to let the hcg in your body build up...even though you may have concieved last week your body may not be prossesing enough to make a positive test...wait a couple day to test again and i wish you tons of luck, dont give up!! :)
