I had sex with my boyfriend February 16th during my ovulation then on the 28th I noticed i started what was to be my period because i was cramping but i wasn't having any blood and all of my periods when i have cramps i have heavy very heavy blood but this time it was extremely extremely light. i'm not on birth control or taking any kind of medicine. i had this period from the 28th (or the 1st of march) until last night. the last 2-3 days of my period i was having brown spotting.. i started having mild nausea with an urge to vomit, my stomach hurts a little now, i've had diarrhea the past 2 days. and i am also having slight weight loss going on even though i'm eating regularly.. my nipples are sensitive and sore to the touch and i also have raised like bumps around the areola of my breasts.

is it possible i could be pregnant or is there something wrong going on? i have never had this happen before! i'm worried about it but i would be so happy to have a child with him and he said he would be happy and gratefully accept!

also, when would be the best time to take a home pregnancy test??
