im not too sure

So lately i have been showing signs that im pregnant. we didnt want to tell anyone til we are sure including my mother. she is a constant worry wart. she has to worry about the craziest things. she flat out asked me if i was and i couldnt lie to her. i told her that im not sure. wont find out for another couple of weeks. she freaked out like i am and that there is no way that we can support it. we already have a 2 1/2 y/o. she's freakin out financially. right now, im not worried about it. for one, we are not sure if i am. two, we have gone this far and hopefully if i am then im hoping for a boy since i already have everything for a baby still. i have friends that have boys too so we are constantly changing around clothes. our place is small but people have grown up in worse places just fine. our son is growing up fine now. i just dont know what to do about mom. she is going to constantly worry and not sleep at night. i wish there was a way to stop worrying about us. it drives me nuts!!!
