So im now a month and a half late on my period.. Taken numberous hpt's and all say negative.. But the last few have been really cloudy in the screen.. And cant hardly tell wut it says.. Except the very last one.. It was really really cloudy.. But my hubby and I both think it says positive... Ive posted here b4.. So if you wud like to kno wut I sed b4.. Just take a look at the last posts ive done. But if not then heres how it all started.. This is why I first thot I was preg... Missed period, brownish spotting for a few days around the time I was sposed to be on my period, lower backaches, cramps, sore breasts, darker nipples/and a lil bigger sometimes, super thirsty, pee more than usual, got really tired and liked to sleep alot (i usually cant ever sleep), gaining and losing weight, smell things stroner than usual, my belly has felt different.. Its kinda harder, swells up sometimes.. And to me it just feels really different than it always has.. It feels wierd.. And ive felt like im gonna throw up sometimes.. I never do.. Just feel like I am....... But lately, its just that my back has been hurting, pee more than usual, wieght gain/lose, tired, sick to my stomach sometimes, breasts sore/nipples darker/bigger, smell (ill smell things and it will make me gag, things like garlic bread-- I love garlic bread!- and stuff like that, eardable, and my stomach has just felt heavier or like somethings different about it........ But my hubby is going to iraq in a week.. And im a manic depressive, and very dependent on him... Ive been really really stressed out.. Cried all the time... And just depressed... So I dont kno if im pregnant, or if its becuz of stress... I havent been able to get to the doctor yet.. So im still very concerned.. And I dont kno wut to think or anything... I personally have this feeling deep down that im pregnant... So im not sure.... Oh and one more thing... I caught a cold or the flu or something.. Im just now starting to get over it..
