Hello, and I hope I can help you today.
Pregnacare Conception is simply a combination of
vitamins that help a woman have a healthy
pregnancy from conception. It has no
hormonal effects and should not have any impact on the regularity of your cycle nor your ability to conceive,
It is not unusual for women to bleed on and off for even 6 weeks after a
miscarriage so the 19 day bleeding episode you had may not have actually been a menstrual period but still could have been bleeding leftover for your D and C. So you may not be "late" at all, but may just have not had a real period since the pregnancy. There is no reason to assume you would have problems getting pregnant again since you have conceived naturally twice in the last year.
Either way, the Pregnacare Conception vitamins have nothing to do with your irregular bleeding. It is generally advisable to wait to try to conceive again after your first real period- so I would wait until you bleed again to resume trying to conceive. If you do not get a real period by 3 months from your last bleeding episode, you should follow up for your GYN for a re-evaluation of your hormones and treatment with
progesterone, which can restart your period cycling.
I hope I was able to adequately answer your question today and that this information was helpful.
Best wishes,
Dr. Brown
