i am now on my 3rd week of femcom and i don't know what to think....

i am now on my 3rd week of femcom and i don't know what to think. I have recently moved to england from america for school leaving behind a 3 and a half year relationship with my boyfriend(staying together though) and family and friends. I have felt depressed since about the second day i started it. I cry every day and just don't feel like myself. Im not sure if that's the pill or the homesickness but i think it's both. Ive actually lost 5 pounds since being on this since i have no appetite now. the depression i feel is going away but ive had bleeding for about a week and a half now. I just wanted to know how long the bleeding/spotting lasts for and will that offsett my period which is due in 1 week now? thanks so much guys....oo and how many months will the irrgular bleeding last?
