I think i might be pregnant but im not for sure, i havent missed my period yet but my breasts are very tender and are kinda enlarging or getting swollen. its hard to tell cuz sometimes but not all the times before i get my period this happens. im also having bad lower backaches and mild upper backaches. my ribs also ache. ive been getting headaches which i usually never get, i have this ringing in my ears and i never get this. lately ive become very tired even if i slept like all day. l have been eatting more but sometimes if i eat to much then i get kinda sick to my stomach. I was pregnant a year ago and had an abortion and many of my symptoms are the same but not all and ever since my aborion sometimes before my period i get bad cramps and lower backaches, and my breasts get alittle bigger.
