4 months after failed IVF cycle not right.

Hi guys, I just wanted to see if what I'm experiencing is 'normal'. I have always had quite heavy horrible periods before my IVF but now they are alot lighter and I'm not entirely sure I have been ovulating. I'm going to test this month I did need a break from TTC after the failed cycle, but prior to IVF I new the signs for my body around ovulation. 4 months on should I still be effected do I need to worry? Any advice is much appreciated, I'm supposed to be starting another round soon x
