could i be? or is it just me?

hello my name is kim, i think i concieved on the 24th or 25th of may, the first day of my last period was on the 11th or 12th of may, i usually have a 31 day length, and my luteal phase is at least 15 days, i have recieved my last period this month on the 12th of june, but it only last me 3.5 days. it wasnt heavy and wasnt light, it was just in between. no over flows no blobs, but lately i feel pregnant, my nipples get tingly now for the past couple days. and i get dizzy but not alot, i do get sick but that also doesnt play a big part in this feeling i have. i sometimes but its verry rare that i feel this way that i feel like im about to faint, and i get tired. but i think i only get tired cause i dont get enough sleep cause my fiance is out to sea (navy) and i cant sleep without him. but im not sure if i am preggo.or is it too early to tell? thanks
