I'm 41 years old and on the 28th of August started feeling nauseated, fatigued, swollen breasts, food cravings. I've been nauseated around the clock since then. I've been sexually active but have used condoms for protection. Last month my period started on the 15th. Yesterday which was the 6th I started cramping and having a gel like blood stain which turned to a brownish discharge by the end of the day. I continued to have cramping like a mild period. Today I woke up and I have a bright red blood flow. I have been so dizy and nauseated. My breasts are very heavy and swollen. I have had also some pain on my left side. I feel quite shaky at times and have to sit. I find it hard to believe that I could be pregnant. I thought I was okay when I got my period this morining but I still am so sick and tired. I'm concerned it could be something serious. I've had two previous pregnancies so I know that I feel pregnant. But know that I'm not. I did take a pregnancy test on the 2nd which was negative.
