in or out?!

Still don't know if I'm in or out :-(15DPO and CD32... All tests have been negative. Actually feeling disheartened by them all. Symptoms so far have been unquestionable. Cramps and twinges along with temp dip on suspected implantation. Boob hurt like hell - even painful walking to loo at work. Have also had bad montgomery tubercles on both. Belly has had pulling sensation behind belly button. Sore throats randomly. Had brown mucus blob day after I suspected implantation. Temperature has been constantly elevated (other than implantation dip). Was initially bloated and gassy but that has eased off. Also had pains in back (although I'm not sure if they are attributed to my sciatica, but that was under control and no pains since early this year). Yesterday and today my urine has had a distinct sweet smell which is totally different from normal and Googling tells me this is also an indication of pregnancy. Have also had tiredness as in bed when home from work and a lot of wetness earlier which has since stopped. We had a good chat last night and decided that we can't go through this every month :-( I for one can't deal with the pain I have in my boobs.

Anyone else had this experience?
