What Are Symptoms Of Failed Abortion And Miscarriage?

Good Afternoon. On Dec 3rd 2013 I had an abortion. This was very hard for me emotionally, and I have been very depressed, but that is not my issue. My husband and I have not had sex since before the procedure. I have had continious spotting since the procedure and have had only one mentral cycle since. Last week I realized I should be starting another cycle at any time. This may sound foolish but since the procedure I have felt that I am still pregnante. I know it sounds stupid, but I really felt that my body thinks im pregnante and its taken all my will power to not waste money on a pregnancy test just because of a "feeling". so i have tried ignoring this feeling. I chopped it up to depression over the situation. on Monday 2/3/14 I knelt down to pickup something and as I stood I felt fluid pour down my leggs and I thought I was urinating myself but with no sensation urination. I looked down and blood was all around me. I made my way to the toilet and when I sat down blood poured faster as if I were urinating but was clearly from my vagina. when it stopped flowing I sat there for a minute in worry, I had a slightlest hint of cramps at that moment and a urge to push came over me, so I pushed and I felt several large clotts come out. I have passed large clots before, but I have never felt anything like this, or passed clots this large (each clot was about the size of a teaplate, some larger). within a couple hours the bleeding stopped and I passed no other clots. Moving forward to Wednesday, I was in my car and again, I felt the warm wetness as though I had urinated, but again, it was blood. I made it to the bathroom in Mc Donalds an the entire process started again, but with a lot more blood. I had the urge again to push and passed many more very large clots again, in about an hour it stopped. Thursday night I started having bad cramps, and as I stood in my kitchen the bleeding happened again, and I was not even sitting down and the urge to push was so overwhelming, When I got on the toilet and pushed, I passed a lot of very large clots. It was almost like having a loose bowel moment the way it all came out. I became very scared at this point but unsure if this was me over reacting. I was scared to pass anymore clots, I found myself clenching my body to keep from passing any more clots and went to lay down hoping it would prevent it, I was scared what would happen if I gave in to ths urge to push, the pressure was so intense that I cold just feel whatever was waiting to come out was going to be large and I did not want it to happen. feeling these clots leave my body was so intense and frightening. Since then I have tried to stay off my feet. I have had steady bleeding and only passing small clots (about the size of a silver dollar coin), but today I have really bad cramps and have had some heavier bleeding then the past two days. Could this be a failed abortion and miscarriage? what other medical issues would cause this type of bleeding, can I loose too much blood? any insight please. My GYN recently retired and had a new young doc take over the practice, I have yet to establish with the new doc, and ddnt want to go to the ER unless I absolutly have to. so i cant really call the emergecy number for the practice because this doc does not know me. Any thoughts.
