Help me ladies!

The periods listed on there seem pretty normal, but some days it's would be just light through out all 7 days or how ever long it lasted.

Some didn't last long, skipping a month, it is just crazy I guess you can say. They seem normal but they aren't normal at all! We have been TTC for 3 years already and haven't had any luck! Back in August 2016 my period would last the whole month and would continue like that the following month! It would go away for about 3 to 7 days and come back for a whole month again. In December 2016 the night before Christmas i bled through a whole 36 pack of ultra tampons! Had to go buy some more! Well it calmed down a few months later so it got to the point where it didn't come for months!!! It goes on every now and then but I never know what to expect!!! I have told my situation to a former classmate and she said it could possibly be I might have endometriosis cuz it sounded similar to what she went through and ended up with endro ... so has anyone experienced this before that could tell me there experiences. i guess you can say I started my period today cuz when I wiped I seen some blood and a small clot well only when I wipe it's pink but I don't have to put a tampon in cuz it's nothing really more like spotting!!! Ugh I wish I knew what was going on with me 😔 I pictured myself with 4 kids by now! I'm losing faith...
