So I am totally confused. I had a miscarriage at 7 wks 1 day, it had a very slow heart beat (naturally no d&c). I bled for about 4-5 days. It was awful, I went to the emergency room and diagnosed me with a threatened miscarriage. It has been a month and still no period. Even though the DR. advised me to wait one cycle I have had intercourse with no protection quite frequently. I also have pregnancy symptoms, frequent urination, fatigue, strong smell sensation. Also when I was pregnant before I would walk up one flight of stairs I would be out of breath, when I lost the baby I was back to normal, now I am experiencing the same symptoms. My hcg levels dropped to zero a week and half after I visited the ER. I have tested twice and I have received both negative tests. Before this I have had irregular periods but always had it every month; never skipped. What are the chances of being pregnant? and how soon can I re-test?
