am I pregnant?

Morgan • I`m 18 && blessed with the love of my life!💕 Hoping to have a beautiful little baby soon!🙌🏼
My boobs have hurt for weeks. I've had crazy cravings and headaches and cramps. My boobs are swollen and I believe my nipples have turned brown. I took 3 test today 2 this morning and one about 10 minutes ago. Two were faint positives and one was I think a negative. Opinions?
