Confused

Ive been having a unusual period for the past 2 months. If you see in the picture theres a month that before my period i got another period after 9 days. After that every 18 days, before that i can have my period every 32 days or 25 days. Trying to get pregnant for our second baby and im stressing. Ive been having a sore nipple for a week and yesterday night i got pink spotting but this morning i have a heavy red blood so i guess its a period. Just want other people to share their same experience here. And know how they dealing with this when trying to conceive
