OPK/HPK confusion/frustration

Ugh. I thought I was 7-8dpo today. I never got a true blazing positive this cycle but figured I must have missed the window when testing. On a whim, I decided to test an opk tonight and of freaking course it’s positive. I then took an hpt and stupidly a FRER. What the hell?! I’m so frustrated because we didn’t even really have sex this week- only once last night. I just feel like I totally screwed this cycle up and I’m so bummed that we didn’t have more sex this week (it was a stressful week with a sick toddler) and that we now have to start the TWW all over again. Ugh. Any and all advice, comments, hugs welcome. 😩😢
