What causes spotting despite having negative UPT?
Most probably a starting of your period.
Thanks for trusting us about your health care.
I can understand your concern here.
This spotting can be most probably a starting of your menses.
The chances of pregnancy and implantation bleeding are less as your pregnancy test is negative after 17 days of your missed period date.
So in this situation you will get your menses with in a few days.
There are so many reasons other than pills which can change your menstrual cycle like stress, anxiety, excessive weight changes and exercise.
Hope it is useful, feel free to discuss more questions.
I haven't had any significant changes in my life as far as dieting , major weight loss or weight gain, any excessive exersise either. The only thing is I'm on antibiotic for the past 5 days amoxicilin and metronidazole both 250 mg prescribed by my dentist. On Saturday I took prescribed medicine for suspected yeast infection.
Get a blood beta hcg and TVS.
Sorry for the delay in my response.
Yes, it is possible that your ovulation may be delayed.
So if you want to sure whether it is due to implantation bleeding or not, you should go and get your blood beta hcg testing and TVS scan done to rule out pregnancy.
But in my opinion you should wait for your menses at least for 3-4 days before going for further investigation.
Sometimes use of antibiotics can change menstrual cycle.
Hope it is useful.
