Okay so I have a question. I'm 3 days late and ttc for a month. A week ago I had brownish pink spotting when i wiped only and now I'm 3 days late with negative hpt yesterday and slight cramping in lower abdomen. And last night after I had sex I went to the bathroom and when I wiped I had two BB gun pellet size blood clots on the tissue. I wiped two more times and no blood. Can someone tell me whats happening 😁
