My regular cycle period is 28days. I ve taken Menodac 75 iu inj as advised by my docter from day 7 - 10. I used to get pain during my ovulation @ day 12 &13. I have seen light bleeding on day 28 for only one day and i didn't feel the ovulation pain this month now today is day 20. I ve tried pregnancy test today morning but got negative result. Could anyone tell me what could be the reason and please suggest me a good gynecologist in Hyderabad.
