Question

Has anyone gotten a positive at 13dpo with an irregular cycle? I was suppose to start my period today but no cramps just more creamy CM. I’m at work so I can test till I get home but I tested last night and it was negative so I assume it will be negative again... I’ve had a headache every day since 7dpo and that never happens. I just wish my hormones would act straight again instead of being l over the place since my miscarriage in September. The struggle is real. Yes I’ve tried OPKS and they did work for me so yea...
