For 2 months I have missed my period, I took 3 pregancy test and all of them came out negative. I waited one more month and the 3rd month I started spotting for a couple days than it stop but 2 days later it came back, but then after it stopped and I haven't bleed since. After a couple days after spotting my breast have become tender and sore and I've been bloating constantly, my period was soppuse to come on the 19th of this month but it didn't. Im not sure if its coming later on, but I'm really confused about all this right now, need advice fast! By the way I am sexually active with my boyfriend and I am 18 years old.
