if you had milk on your breasts you arent pregnant, you just simply spilt milk on your breasts. and even if you are pregnant you dont get milk in your breast till like the second or third trimester.
just because your boobs get bigger doesnt mean your pregnant. it just means your boobs are growing. and your boobs dont really grow until your milk comes in or around the second or third trimester.
and if your stomach is getting tighter it doesnt mean pregnant. when you get pregnant your somach gets larger not smaller.
you do not get your period when your pregnant. and the first sign of pregnancy is a missed period....not milk on your breast, tight stomach, and large boobs.
you got your period 6 times last month????thats a sign that somethings HORIRBLY WRONG! not that your pregnant. i would go to the doctor ASAP and have them see why you got 6 periods in a month. most periods are 5 days long ....so 5 days long, times 6 periods....THATS 30+ DAYS YOU WERE BLEEDING OUT OF THE MONTH...........SOMETHINGS WRONG!!
It wouldn't hurt to do a pregnancy test. What sort of bleeding did you experience? Normal period bleeding or light spotting? Sometime you can bleed in early pregnancy. Do you have any other pregnancy symptoms?
