HI, Thank you for your query. I understand your concern. You seem to have lactational amenorrhea for all these days. THe cause of your pink discharge can be- Lactation is known to be associated with irregular bleeding . - Getting back to normal menses after stopping breast feeding.. the bleeding tends to be irregular, changing pattern for few months. - If you are sure about ovulation,in last month & had unprotected sex.. possibility of pregnancy is there... in such case pink bleeding after about 8-10 days of ovulation can be implantation bleeding. Home pregnancy test would be +ve after 8 days post date of menses.The test you had done might have been earlier to be +ve. - Apart from this routine causes of such bleeding including cervical erosion/vaginitis/ pelvic inflammation / cervical polyp need to be excluded. * you should get pregnancy test done after 8 days delay in expected menses date.( about 3 weeks from ovulation )This would confirm/ exclude pregnancy. If it s not.. consult a gynecologist for further evaluation of health. Thanks.
