Ok so I am feeling really nauseaed, I'm going to the bathroom like 4 times in an hour, I have vomited once, my lower back is hurting, and my nipples are really sensitive and my crest is hurting(maybe heartburn). If I am pregnant I would be 2 weeks, I was a day late on my period, but for the last six years I have gotten it every four weeks on Wednesday. Its Thursday and this morning I started discharging brown watery stuff now when I wipe its really lite red and very little blood that's not usual for me. I have taken 2 pregnancy test and they say negative but I'm not sure if its two early to take them. Should I go to the doc and get a blood test or just wait and see if my blood flow gets heavier?

Sounds like the beginning of your period to me. Sometimes we are late for no reason whatsoever.

Heya my chest is been very sore past few days and I don't know why

Usually the nausea comes at the 6th or 7th week of pregnancy
