Pregnant after chemical

Claire
Hey guys! So after 7 cycles of trying we had a chemical pregnancy last month on November 11th. I decided to take my mind off of it for a month and not temp or actively try and just focus on my hubby. We went on our anniversary trip and had thanksgiving etc, now we're back and my boobs started getting sore. Yesterday was when I was supposed to start my period but I tested and it was positive! A really strong line as opposed to last time! I'm scared out of my mind because a lot of girls end up having a second mc because it's so soon after, others say your more fertile. What has been your experience?
