Hi im new to this app. im looking for some "Peace Of Mind" lol im currently 4 weeks pregnant i have had 3 possitive pregnancy test & i am worried sick :'( . The year before last i had a miscarriage at 8 weeks the last year i had a chemical pregnancy.. Now here i am pregnant again finding it hard to be excited thinking that something will go wrong again... My breast are very tender & everyday a have a few crapms here & there some worse than others. I seem to get very light headed & hot every time i stand up. once & a while ill have lower back pain & i have to pee alot. Is all of this normal?. The cramping scares me really bad. I just want things to go right this time & to have a healthy baby. Has Anyone had these happen & continue to have a healty pregnancy? Any advice? Sorry for such a long post. Thanks In Advance.
