Question : Hi i stopped using birth control on May 1st and had my period May 3rd. Then i had sex several times since but i havent had my period since. I have taken 3 pregnancy tests all negative. I suffer from endometriosis so that is why i have used birth control non stop until May because we try to get pregnant. But could i still be pregnant even though my test says nothing we last had sex on May 17th or is something maybe wrong with my period?

Brief Answer:
should consider repeating the test

Detailed Answer:
HI, thanks for using healthcare magic

Pregnancy tests detect the HCG hormone, this is normally detectable by day 11 to 14 after conception so it is possible, if the tests were done before this time, that they are falsely negative.

You should consider repeating in a few days just to give a little extra time.

Endometriosis itself, is not normally associated with delayed periods.

There are other causes of delayed periods such as : (a) abnormal thyroid hormone levels
(b) emotional stress or illness
(c) high levels of prolactin hormone
(d)physical illness
(e)polycystic ovarian syndrome

I hope this helps, feel free to ask any other questions
