Cycles were irregular since the first times. But it went really crayz in this last year. Sometimes 20-30 days sometimes 60-70 days (Im on my 76.th day and no AF). Last week I went doctor and she said there isn't any problem with my uterus or ovary then took a blood test for hormones and no anomaly again. I have never used any pills and I am 25. 4 month on ttc. I dont want to lose hope but that long cyles, not knowing my ovulation times and couldnt find any causes even in hormone tests make me nerveous, like fighting in darkness. Is there anyone went through things like these, or who become preggo in situation like this...
