Out of country

So I don’t post at all but I’m starting to get concerned. At the begging of last week I had ended my period. Conveniently it was in time for me to travel to Peru. So I had ended the exact day we left. I went all week in Peru with no problem. But on the way home I had some bathroom issues to say the least. And I had started to notice blood when I wiped. So as I normally do in this situation I put on a pad just in case. I knew that I had just had my period this month so I figured it was from the amount of wiping I had been doing. Well the next night I had gotten woken up with extreme cramps probably some of the worst I had ever. I woke up the best day looking like a victim of a massacre. There was more blood then I’ve ever seen come out of my body. Over the last three days I’ve had probably the worst period I’ve ever had. But what I still don’t understand is if I had it not more then a week and a half ago. Why am I getting one now.

So sorry for the long and probably gross story. But I’m starting g to get really worried and I want to know if anyone else has had this problem and if it’s something to be worried about or is it normal?
