11 dpo

I tested at 11dpo there was no line not even faint. I got a positive on ovulation test and I'm just not feeling very hopeful. I'm having very full feeling boobs, Also sensitive. Headaches and just overall exhausted and this morning I had a taste in my mouth like I sucked on a penny I've never experienced that with my previous pregnancy so super weird. I'm supposed to star my period Friday. Are there anyone who got negative but then positive around 13dpo? Or am I considered out this month?
