So I started bleeding on Saturday and finished on the same day, and up until now I’ve just had very light brown spotting. The day of bleeding I had was pretty heavy, so I am pretty sure I’m not pregnant, but I also had some weird stretchy clots. One of them was kind of large, maybe 2cm. I also had INTENSE pain and bad nausea, which is really unusual for me on my period. I think it’s possible I had a miscarriage without even knowing I was pregnant. Help?
