Opions symptoms and conditions

I have started using NuvaRing within the last couple of days and I am worried about all the side effects that I am reading about. I am bleeding very heavily and thought it was just because my body needs to adjust to the new bc. If anyone out there has had a good experience or had side effects that actually went away after you got used to it, please let me know. I don't know if I should stay on this and give it a chance or if I should just stop now because it isn't for me. I do love the ease and convience of the ring though. I am also very concerned about having sex. I don't know if I should just take it out before or try to have sex with it in. My bf is very large and I am sure he will feel it, but they say that most men that feel it don't mind it because it is so soft and flexible. I don't want it to fall out though either. I just think that taking it out everytime before will be a pain. If you have been through any of this and have any comments or information that might help me, please respond. I am really hoping to get some other peoples opions. Thank you!!!

I am 2 weeks and 3 days into taking this pill for the first month and I don't know if I should stay on it. I just started to get brownish blood/spotting and cramps in my back. I am afraid I might be pregnant although my boyfriend always pulls out on time. There is a chance that some precum got inside me, but I haven't been too worried since I don't think it's very likely to get pregnant from precum while on the pill. Should I be worried or are these symptoms normal? I also have had more frequent mood swings and anxiety, but I suffer from both anyway. From all the bad things I have heard, I am eager to switch back to Ortho-Tri Cyclen. Is there a big difference between the pills and the amount of protection they offer from getting pregnant? If any information can be given, I would really appreciate it.
