So confused and hopeless

Samantha • Wifey❤️ - Due 9-2-18 with our Rainbow Baby!!
Even though I haven't had luck with getting responses on here. I'm going to post this anyway in hopes someone will have an opinion or some much needed advice/support. 
 I'm losing hope that my body will ever get normal so my hubby and I can conceive. 
Here's a back story. 
Back in July we had an unexpected ectopic pregnancy that was terminated in August. I went back on the pill the day of the procedure after being told that it would help regulate my cycle again. In September I had no period but had the worst cramps of my life. Again no period in October and again terrible cramping. November came and I had one day of light bleeding and cramping again. December came and my doctor finally saw me. December was finally the month we decided we were going to try again to Concorde because we want a family. I was told at my appointment that the bcp prevented my uterine lining to re build which explained the horrific cramps. I was told that within a couple of cycles off the bcp I should be ready to conceive. 
January AF was 8 days late then finally came. February she was on time but still light. All ovulation steips were negative. And that brings us to March. AF was on time and heavy. I got a very positive opk and the dr agreed I was in fact finally ovulating. Day 16 of this cycle I started spotting while ovulating!?!? Weird right? Well today is cycle day 22 and I'm STILL spotting/ bleeding. And according to my ap with the amount of blood it was a period so I'm also on cycle day 5?? 
So frustrated and confused. 
Has anyone experienced anything like this?
