Help me

Okay so help what do you guys think I should do. A little back story I was on the nexplanon back in 2016 when on it it was horrible I never stopped bleeding a complete mess. I get off of it and only see my period 3 times in one year. After the year is up to give my period the chance to go normal I get my period faithfully every month . Than back in November my period came on at the end of the month so it was on a couple days in the beginning of December .than I missed all of January and it came on at the end of February beginning of March ..that really freaked me out bc it was normal for a year like why start acting crazy now . And so than now again I’m almost a month late ☹️☹️ and the worst part is I am trying to get pregnant now. I wanna go about things the natural way before I automatically go to meds . Like all organic eyes remedies and vitals as well as working out . So any food diets you guys did to get pregnant any tips ? I wanna baby so badly 💕it’s breaking my heart bc I know my fiance is really waiting for one
