I have a great deal of pregnancy symptoms(food aversions, sensitivity to smells, enlarged breasts, blue veins noticeable in breasts, stomach, arms, nausea for a month, swollen hands and lower abdomen, feelings of movement, dizziness when I stand or rise suddenly, etc...I have two children already but my question is: I would be almost 5 months pregnant and for two months I bled a couple of days and would stop, now this month I had a regular period. Can you be pregnant and bleed during the time of normal menstration. If not, what is wrong with me that could signal all pregnancy symtoms? I took an ovulation predictor test on 5 days throughout the month and it was constantly positive. I also have taken pregnancy tests and a couple were very faint positive. I am so confused. My obgyn gave me a diuretic for swelling, had my blood sugar, thyroid, and hormones checked and all came out find. Please help.
