Pregnancy Info HOME

I've been trying to get pregnant and since I have started trying my period is all messed up. Sometimes I go without a period for 2 or 3 months but then go to the clinic and find out that I am not. Well as usual I am late. My last period was on Sep. 13th but I didn't want to get my hopes up this time so I just didn't worry about it. I've started the frequent urination, extremaly tired , br___t soreness and all. But I've had that all b4. Well, now I have a big brown ring around one of my nipples and they are swollen. I am also very sensitive to smell but had a light case of that last time that I was late but this time, I can smell things that no1 else can and it gives me a head-ache and makes me nauseated.. I've only got sick once and I think that's bc I ate too much and got up to fast. Plus, it doesn't take much to fill me up.. 2 pieces of toast and I am full.. Yes, my period was very regular b4 but that was when I was using condoms. Since me and him have been together which is almost 2 years, we have never used condoms and about 4- 6 months of being with him is when I started having problems just the days were off but here recently, I have been known to go without one for up to 3 months. I don't know what to do. I already have an appt. with the clinic on 12/14 due to my pre cancer cells but this time I am thinking that there is more going on. I'm not wanting to get my hopes up. I'm not even in the mood to have s_x. We normally don't go more than 2-3 days without s_x but it's been almost 2 weeks and I still don't want it. I wasn't really worried about it untill I noticed the brown ring around my nipple and also that they are swollen.
