my friend is currently 8 months pregnant and she just found out 2 months ago and even to this day she does not look pregnant at all, she has had 3 ultrasounds since then and they cannot see the baby's sex or a clear picture of the baby, there's still a heartbeat and she still tests positive...
I've done a lot of research and implantation happens about 5-10 days after ovulation so testing tomorrow morning can actually give u very accurate results... Im gonna test Friday morning its my 10dpo! Good luck and lots of baby dust!
