Irregular period

Since February, my periods have been irregular. I believe it's due to stress. I skipped my period in March and experienced a prolonged (more than 7 days) period in April. It was weird because when I wiped there would be blood, but it was not heavy enough to transfer to a liner/pad. It mimic a regular flow in terms of color. I got another period 38 days later (compared to the 52 days), and it lasted approximately 8 days. But it was different from all the periods I've experienced. It was bright red with some clots and the flow was pretty much the same till the end. I've had clots in the past, so that's not new to me. I'm a little stunned because 6 days after this period...I started bleeding again! I recently had a Pap smear prior to my period in May and it came out normal. I'm wondering if I need to go see my gynecologist again to have my irregular period checked out. Any thoughts? Have any of you guys experienced this? Another note, I thought I had cysts back in October 2014 due to lower stomach pain. My gyno checked (not via ultrasound) and no cysts were found. I hope everything is okay and my period is just really riding a 'stressful' roller coaster.
