Hey, I am a 19 year old female. I weigh 240 and have for a long time. My period in June started on the 9th. In July it started on the 15th. I have missed August and so far missing September. I took a test on September 9th, it was negative. My breast are tingling/burning. My nipples are sore. Im tired most of the time. Could something be wrong? or could I still be pregnant? I am trying to conceive so we don't use contraceptives.
