Hello and welcome,
There are many reasons for this.
High levels of the hormone
progesterone produces symptoms of nausea,
vomiting, weight gain, sore breasts similar to
pregnancy. So this may be due to the implant. A course of estrogens helps relieve these symptoms in some women while some may need to remove the implant.
Another cause is pseudo cyesis where there is no pregnancy but women get pregnancy symptoms.
Hormonal imbalances of the thyroid as well as the female reproductive hormones may also lead to similar symptoms.
Pregnancy tests come positive when the pregnancy is atleast 3 weeks. So you may wait and repeat the tests after 3 weeks. If it is still negative, then pregnancy is ruled out. Other option is to see your doctor and get evaluated and may get a
blood test or a scan to rule out pregnancy. The evaluation will also help determining the cause of the symptoms and then help in further management.
So do not worry just get an examination.
Hope this satisfies your query.
Thanks for using HCM.
Feel free to ask any more questions that you may have.
