it is due to plan b.
Detailed Answer:
Dear XXXX, welcome to HCM and thanks us.
I have gone through your question in detail. Chances of you being pregnant are not there as plan B is a very reliable emergency contraceptive. Morever, all your tests are showing absence of pregnancy. So don't worry about pregnancy.
Regularity of menstrual cycle depends on hormone balance in body. Plan B or any hormonal contraceptive disturbs this balance. This imbalance is a factor behind your irregular period. Body takes time to correct this balance, sometimes upto three months. However if it is troubling you much, you can go for hormone study and ultrasound scan to come to a exact diagnosis.
So you have to wait few weeks more.
