1 MC...2 chemical pregnancies...HELP!

I had a miscarriage in June at 10 weeks, had it taken care of medically. I bled for a months and a half and after my first period, decided to try again. The first month, I was 2 days late, took a positive pregnancy test and 5 days later, started bleeding. We tried again the following month and exactly the same thing happened!!! I also took a positive pregnancy test the day I started bleeding again. I know a lot of people have it way worse than me but I am just getting frustrated, is there something wrong with me?! If anyone has any insights, I would love to hear some of your storied...thanks in advance!!
