okay so this journey of mine began a little over 10 years ago I'm 30 now and got pregnant with my first child in 1999 that pregnancy ended at 24 weeks due to preterm labor and delivery and my little girl died at 1lb 1/2 oz:( since then I have had very abnormal menstrual cycles and my partner and I started trying for another baby in early 2004. I was placed on 50 mg of clomid and discontinued after 1 cycle. I recently resumed fertility treatment in 2008 and last year was placed on 100 mg of clomid and metformin and discontinued after that first cycle due to a loss of medical insurance. I was having regular menstrual cycles from that day forward. my last mestrual cycle was 08/15/2010 it appeared to be normal and lasted 7 days. I resumed sexual activity the day I stopped bleeding and several times throught the rest of the month. In September I had no period took 2 ept's and recieved negative results both times, but this month I started experiencing headaches, severe moodines, extreme increase in vaginal discharge, enlarged and sore breast, and a few episodes of nausea, my nails are also growing at a rapid pace and I've been fatigue off and on. Could it be possible to be pregnant and not know it?
