two days ago i had implantation bleeding and took a test later that day and came back positive. according to apps i’m 3 almost 4 weeks pregnant. two days later (today) i’m having light bleeding mostly brown/dark red. no cramps or abdominal pain. does anyone know what this could be? i called my doctor and she said it could be from the recent intercourse but not to worry if i don’t have any pain but here i am worrying. lol if someone could help that would be great!
