Ok guys so I have a question about my current situation... so April 18th was the first day of my last period, but my period that month was about a week and 4 days late but it came. I have not had a period every since April. I've experienced missed periods before, but that was when I had the birth control implant and that was in 2015- January of 2016. Once it was removed and my hormones went back to normal, my periods were regular. I knew something was weird when my period came late in April but i ignored it because it still came. All of may went by, and I had no period. I went to the doctor for a pregnancy test, and she told me it was negative. She also asked if I knew anyone in my family who showed negative on a test but still came out pregnant, and at the time I said no because I didn't know, but I just found out when my sister was pregnant, she had a negative test by the doctor but the next day took three home tests and they were positive. The nurse told me not to rule out not being pregnant because some women don't show positive until 12-16 weeks in. I've was experiencing really bad cramps last month and back pain and felt like I was coming on my period, even felt like I was bleeding, but when I checked it was only discharge. It June and I do t have the cramps as much, but every now and then, but still no period. I've been very emotional lately but was told it may be from the lack of sleep I've been getting. I'm not sure what's going on. Any ideas? If anyone knows or has at least the slightest clue of what's going on, please let me know!
