I wouldn't worry about who the father is until you find out that you are actually pregnant. All because you have the timing right and had sex doesn't mean it worked either time.

If you are pregnant, you can wait until after the baby is born and get a simple paternity test to solve the issue.

Thank you for your comment.
I am not pregnant. I was 10 days late though... wonder why as I was not really under any stress or anything unusual. I guess my body is still getting used to being off the pill. I will keep trying!!

i was on depo provera for 3 years.the last time i had it was january 07.i got my periods back in july until october 16th. i was on for constantly 3 month. me and my partner split up on the 9th october. i went with another boy until the 24th. i did a pregnancy test whcih was negative. i got bak with my partner the 26th. i bled from the 27th-31st. at first i didnt think this was a period. i then did a pregnancy test the 6th november.this was negative. me and my partner were sleeping together everyday from when we got bak together. i did another preg test on the 1st december whcih was positiv. is there any way the bby could be the 1st boys? if i had normal periods i would be ok but due to me coming off the dep provera i dont no when i am suppose to ovulatet. the midwife sed i am due the 2nd august and the ultrasound scan sed the 3rd ... can anyone help? PM me thanks
