G My name is Nicole and I have a few questions, about early detection signs of pregnancy. In my case, it s very hard to tell if I am or not. Reasoning b/c I usually have a menstrual every 3mths. However, the last menstrual was in Aug. My primary OBGYN has informed me that if I don t have a period with in 3mths that she would prescribe me medicine to make me have one. So November comes and I started to notice ONLY a brownish spotting which is very faint but still showing; which is known as Implanation Bleeding. Knowing that you can still ovulate w/o have a menstrual still is a chance of pregnancy. Other symptoms that I ve notice is, the Hot Flashes, Nausea but can t throw up, Abdominal Bloating, Mild Headaches, change in appetite, and frequent going to the bathroom. I took a pregnancy test which was negative but I believe that it was too early to detect the HGC hormonal levels. My question is, I ll be taking a blood test this Friday to get a more accurate result, but if that still comes up negative, what could case this? But the last time that I had my menstrual I didn t feel like this, and a Woman knows her body due to unusally changes if this has never occurred. Thank you So Much

Hi Nicole, Reading about you, it is unlikely you are pregnant, more so as you have a negative pregnancy test. Yes, women with irregular bleeding can be ovulating, but less likely than women with regular cycles, also the symptoms of bloating, hot flushes, nausea, point more towards menopausal vasomotor symptoms. Depending on your age, I would say you are probably premenopausal. It is termed premature menopause if your age is less than 40. I would advise you to do FSH levels in blood, to know if you are menopausal or not. As if you are then, hormone replacement therapy would be treatment advisable to you. Hope this helps. Regards.
