On my period, when I saw 4 or 5 small clots (size of penny). I always had the clots on 4 day of period. Last time, I was on period last month ago, and only have two clots. The first time, began on my period since I was 14 years old without CLOTS until 16 years old and got clots in every period. Always got 5 clots since 16 until 20 years old and then starts less of clots like 2 or 3. Once I lost the clots in ONE day and then the next day end of period. So, is normal or not normal? I can feel the pain when a clots on way to out. I believe that the pain worst while having a clot than a cramps.
