frustrated

so when we decided to have our first I got pregnant as soon as I went off the pill. Now we are trying again and it's not happening like that ik every time is different but it makes frustrated me. With my first pregnancy I had pretty bad pain on my left side I just thought I was ovulating cone to find out I had a cyst and I was pregnant. I am having the same pain and my period was kinda wonky last month so I took one it was negative. Now a month later I'm still having the pain but still no positive test. I have never be so discouraged!
