I had my sterilization reversed on the 5th of nov my period came on the 11th when due and went again on the 17th nov
My fertile days where from 19th until 27th and I had sex with my partner everyday on and between these dates including my ovulation date the 25th
My partners sperm results have came back and he has a high sperm count.
On the night of the 25th I had a bit of brown staining on my pants and again a bit on the 26th there has been nothing today the 28th.
I am really concerned because of the higher risk of ectopic pregnancys and all the rest
Is it to soon for the doctor to determan if I'm pregnant

It is too early for a test you will need to wait aa few weeks at least. If you do get extreme pain at any time though make sure you get medical attention fast. I had an ectopic a few years ago and on the 2 pregnancy after that I just had to have an early scan to make sure it was not in my tube. Good luck

It is way too early to tell either way as it takes a number of days for the fertilized ovum to travel down through the fallopian tube to implant into the uterus.

If you are worried about an ectopic it is still too early to tell as it is a matter of time before the hCG level is built up sufficiently in your body to produce a positive pregnancy test. You will most likely have to wait a couple of weeks before a positive is possible.
