Negative Ovulation tests/irregular cycle?

Kara

So For the past 3 months my cycle has been really screwed up. I will start spotting around the 1st, And it will go on lightly for 7days. I usually stop for a day or two and then it starts back up for another week and half to two weeks a lot heavier. This has never been normal for me. I asked my Dr and she said most likely stress, But these past few months have been the least stressful for me since the past couple of years. Things have actually been pretty good except my cycle. Anyway, I have been testing for ovulation for two weeks from the time I "stop" my cycle and so far have all been negative. We are TTC baby #1.

Any thoughts, concerns, similar issues?
