Four days late cramps lower back pain im i having a baby?

It sounds like you have all the signs of early pregnancy. Alot of times in early pregnancy, it feels like your fixing to get your period. But it is just your uterus stretching. If i was you i would go to a store and get some folic aside pills, It is a vitamin, and you really need it in early pregnancy. folic aside can also help get a women pregnant. I was trying to have a baby for two years, i went to the ob gyn Doctor and he told me to start taking folic acid, and i would be pregnant in two months and he was right. I would get a pregnancy test today and take it tomorrow morning with your first urine of the day. I found out i was pregnant with a $1.00 pregnancy test i bought too and took them both with my morning urine, and they showed positive.i hope i helped. have a good day.
