HELP!! 4 weeks long period!

Amber
Serious period talk here (tmi) Now I keep track like I'm supposed to. Cause I know my period are always wacky. I'm really looking for someone who has similar issues that I can talk to about this. I'm trying to conceive and this is not helping. 
Couple months ago I went to the gyno and he tells me he needs to take blood samples and give me an ultrasound sound make sure I didn't have cysts. Results came back normal. I'm so frustrated!!
