Advice

got my nexplanon removed May 19th and we tried conceiving the following week may 24-27th the 26th being ovulation day and 27th being the day after. It is now June 11th and I am 6days late for my period. I have been experiencing slight nausea without vomit , hot flashes , appetite increase and decrease . Sore nipples (way more sore then usual) And I’ve been cramping since June 2nd until today. I have had pelvic sensations I wouldn’t really call them pains. I’ve also had some shooting sensations in my stomach. I have took pregnancy test multiple times throughout this week and they have all said negative. Maybe I’m still testing too early ? Maybe it’s a Phantom pregnancy? I don’t know what to do at this point. Any advice or tips?
