hi. i have had regular periods for 13 years, since i started when I was 11. i had a baby in october of this year, had the 6 week wait with no cycle, then my cycle started as normal. I had a regular period for 4 moths and out of nowhere in march it stopped. finally in May my nurse put me on something that i had to take for five days, twice a day, and it was suppose to make me start 14 days later, it did. now I am 9 days late, agian , with no symptoms in sight. I have had periods like clockwork and now nothing, i am very afraid that with this problem i will not be able to get pregnant agian. so i am 25, 175lbs, still carrying babyweight, thyroid is fine, prolactin levels are fine, no stds ever, stress level is normal, diet is same as always, exercise everyday. some advise maybe, if any ? one has expierienced this! thanks!
