Long post

Hey everyone I’m new here. Here’s some back story.

I’ve never had a regular period in my life. I was in the shot, the pill, the nexplanon etc. I never stopped bleeding. Maybe a week once a month I wouldn’t bleed. My periods were EXTREMELY painful & I would get the chills, hot flashes, I’d puke, have to sit in the fetal position for hours & is eventually pass out in the bathroom. They told me they though I had endometriosis & to start the pill to help regulate it. I didn’t start it. Nothing ever helped. 12-17. Well in May 2014 I ended up getting pregnant with my now 4 year old! Had her in February 2015! My boyfriend & I have been together 8 years. I was getting overweight because of my shot (got it the day we left the hospital with my daughter February 7th 2015) was on it until March 2018. Got off of it because of the weight gain. We had lots & lots of unprotected sex (we weren’t trying but weren’t preventing) & nothing ever happened. I still bleed horrible but it wasn’t as long. Fast forward to December of 2018, I finally got on the patch because I couldn’t take the bleeding anymore. I was on it for two weeks & I got such bad headaches & heart palpitations. So after I got off of it we decided to start TTC. My periods are now normal!! January 7th-12th, February 1st-5th, March 2nd-5th, April 1st-5th, April 30th-May 4th...but still no luck. I started using OPK in April & got my positive in May 13th..my period is due in 6 days. What are we doing wrong?
