What is wrong with me?!

Katie • 👑Girl Mom👑 5.1.13❤️ TTC #2💞 Living with HS and dealing with fertility issues 💔

For 2 years now my cycle has been a complete whack job, skipping 2-3mo, coming twice in one month, but most just completely random all over the place. This started when we decided to let nature take its course and stop preventing. Was pretty much doing pull out and keeping in time with my PERFECT cycle from June 2013 thru July 2017, no oopsies or anything the whole time.. Back to current.. I’ve had my thyroid checked, I’ve had a full blood panel done, ultrasound, and so on trying to get to the bottom of this, but EVERYTHING has come back 100% perfectly normal. I’m not super stressed, although I’m typically an anxious person, I’ve been this way pretty much for 20yrs now and it never affected me before. OBGYN prescribed metformin, but admitted it probably won’t do much. So trying to figure out if anyone has any more routes to try, my daughter is begging for a sibling and I wanted to be done having kids by 30, 2020 is my 30.. Help?! Advice? Anyone else been down a similar road?
