im pregnant again!

i need to get this off my chest, my husband is still working and i dont want to tell anyone else. im honestly so scared. my daughter just turned 9 months and it took us so long to have her! i wasnt planning on trying again until shes a year and a half! im in shock... i cant believe it still. ive been crying on and off since i took that test this morning.. and i feel so bad doing so😢. please dont judge me, i dont mean to sound ungrateful because i know God has blessed our family again. i wasnt expecting this. im just nervous/scared... having 2 little babies, my baby is still a baby baby😢 can anyone help me out.. i dont remember the last time i had my period. i know it was the beginning of febraury. sometime after the 4th. how far along could i be?
