I need help. So I ovulated 10/11 & 10/12. I had my insemination the 10/12. As of today I am 15dpo. I've been crampy, nauseous, with sore boobs since 9dpo. I took preg test every day since 9dpo all were neg. On 13dpo I started spotting dark brown blood for a half of day. Then it turned bright red. On 14dpo I bled dark red for only like 6hrs then it stopped. I never had a af like this. Usually I get it for 3-4days. What does this mean? I read online that some ppl this happened too turn up pregnant like a week after this. Please give me your opinions.. baby dust to those who are still trying ~~☆☆☆☆~~
