Hello
Thank you for your query.
It is highly unlikely that you had a home pregnancy test which was positive thrice, and the
blood test was negative.
It could have been a very early pregnancy, and by the time you took the blood test, it could have miscarried spontaneously, as often happens, so failed to show up in a blood test.
Normally a blood test is more sensitive in detecting a pregnancy than a urine test.
You seem to having highly
irregular periods.
Causes could be stress, anxiety, weight gain or loss,
thyroid disorder,
polycystic ovaries etc.
Also, after the
implanon removal, it does take a few months for periods to regularize, but 8 months is a bit too much.
Please consult your gynecologist for the exact diagnosis.
Vote helpful if you found the answer helpful.
Take care.
