Have Implanon, Bleeding, Tender Breasts. Negative Tests. Could I Be Pregnant?
Thanks for posting your query.
Your symptoms can be due to pregnancy though it is very unlikely since you have tested negative.
The implant is over 99 per cent effective, which means less than one in 1,000 women using it over three years will become pregnant.
Pregnancy tests pick up hormones that are only produced during pregnancy. Hormones from contraceptive methods won't affect the test.
Its not that overweight females are protected only for 21/2 years. The contraceptive lasts for three years. You will get a smaller dose of hormones in year three than year one but its enough to stop ovulation (releasing an egg).
There is a possibility of your symptoms being caused by hormonal disturbances caused by the infections or antibiotics but then it should not last longer than a couple of weeks.
So , to conclude, the risk of pregnancy in your case is very small and can be ruled out by an ultrasound pelvis.
I would advise you consult your gynaecologist if your symptoms persist for more than a week to get a confirmation by some tests like blood beta hcg or ultrasound .
Hope I have answered your query.
