confused AS FUCK

BackSTORY : I had a missed miscarriage in February, 2 d&c;’s in March .. my HCG got back to negative 5weeks ago (4) I even got negative hpt test... got my first period May 20th to the 28th seemed normal (MY PERIODS ARE IRREGULAR) my ovulation test says I ovulated on the 29th we been having unprotected sex for a WHILE I mean A WHILEEEE !!

At this point I’m lost . Soooo Recently 6 Positive hpt (some different br

ands) blood test was negative at the hospital ? Like what ... then called my OBGYN and she sounded confused as to why the blood test was negative with diff brands positive test. She said maybe it was an error or too early, she hasn’t received anything from my primary doctor yet to confirm what he wants to do...

Soooo not to long ago I took another hpt positive!!! Took a CB digital (NEGATIVE) took a ovulation strip it was DARK positive... took a CB ovulation digital test it was Negative? Wtf is going on ??? I wanna tell my mom and mother in law, as there birthdays are coming up but don’t wanna give them false news 😔😔

My hpt are getting lighter ... idk what to think everyone saying CHEMICAL like ugh 🤦🏽‍♀️🙄
