I am sorry you are feeling so down:hugs:. I just wanted to let you know that I went through exactly the same as you. I went in for numerous tests to see what was going on but as my ob told me some bodies just take a little longer to get back to "normal". I had mid cycle spotting, my af was as long as 45 days but each cycle got a little better and shorter until the month I conceived I ovulated at my pre pregnancy time (used opk's and temping) and that was when my body was ready to be pregnant again. It took 7 months which felt like a life time but it just wont happen before our body says it is ready.
I know it is tough but I know your time will come. Take care!
