Help please!?

Mary
I am sorry if I'm posting this in the wrong topic area...I'm new to this layout of Glow! ? Back in May, I found out I was pregnant with my first! I was so excited, I'd only TTC'd for a month! 
I went to the doctor, and they found a mass of some sort in my uterus, unfortunately. I had to have a D&C (the most painful thing I have ever done, it broke my heart) in order to save myself and allow me to get pregnant again in the future. A couple months later, I was getting normal periods again. The doctor said that everything healed up without any scar tissue, and it shouldn't change my fertility whatsoever. I remember him saying to be very careful, as I will be more fertile for the next few months due to the procedure. 
Now, five months on, my periods are still slightly irregular. I was due for a period on October 22, but I got it 3 days early. I was feeling odd, but I just figured, "Hey, I'm still irregular." The period only lasted about 3 days, unlike the normal 4/5.
A few days after that short period, I began breaking out horribly hormonally (not a symptom of my first pregnancy), which usually only happens 4-5 days before a period. I began having gushes of watery, milky CM multiple times a day (like with my first pregnancy). Also like with the first, I've been having crazy dreams, and been very sleepy. This time, however, my breasts have not been sore, but maybe a little sensitive.
I took one test two or three days ago, and it came out like this (pic attached)...I'm confused. It may have been too early (I don't know, my cycle is complete whack).
Have any of you lovely ladies had a similar situation, or had a friend with one? Input would help. I wasn't actively trying, but I also wasn't not trying. This is very hard for me as I'm still mourning my first child. Thank you for reading. xx
