Why me?

How is it that since I’ve started my period at 15 I’ve had a period on time. I took the pill-it made me depressed. Then i got the depo shot-worsened the depression. So i stopped with the birth control for a year or 2. Then i got the mirena-THE WORST EXPERIENCE OF MY LIFE! Had it for a year and a half. I’ve been off of birth control for 2ish years and have been on time ever since. So i get married to the LIVE OF MY LIFE. We decided that we want to start our little family❤️ well we’ve been trying since February. Almost a whole year and still no baby😭. I’ve had soooooo many faint positives and so many times that I’ve been late (the dr thinks they were chemical pregnancies i see the OB on Friday) my last period was October 8th. I’m now 51 days late. No sign of AF and no positive pregnancy test. I just want answers. 😭😭😭
