I've never had a period this heavy, I'm on schedule for my cycle but about 3.5 weeks ago I had unprotected sex, and a week later my breasts were very tender and sore which lasted for about 2 weeks up till yesterday when my period started the tenderness subsided, but it's been really heavy flowing nonstop, I've went through maybe 7-8 super tampons in the span of 12 hours and A LOT of huge clumping as well, could I have been pregnant without realizing and then had a miscarriage?? Please please let me know something, I don't have a GYN I can go to. Thank you so much
