Day 1 of my period today and I've emptied it four times since 9am. 15ml nearly each time. Going by past cycle tomorrow will be the same, then day 3/4 empty 3 times about 7 ml each time. Then day 5/6 will wear a tampon to deal with the end of it.
Does that seem heavy to you? It looks like so much blood.
Do have a copper coil though
