Irregular Cycle

Marvah
I've been trying to conceive for the past 3 months and it's been hard considering my irregular cycle. I've been getting really stressed out and feel like I'm doing everything right to no success. Does anyone else have irregular cycles and was able to get pregnant? 
Also, for some reason I've been having my period every two weeks for the past 3 times I went to my GYN and she's gonna run some hormonal tests, I will find out this week of the results. Anyone else have this issue?
