My period is always on time and heavy with cramps I always know when it's coming. But this month I missed my period and when I was 4 days late I had really light spotting and brown disharge for a few days. I took a few test all negative. I had alot of pregnancy symptoms. Now I am 17 days late and have gained 6 pounds in a month and went up 4 sizes in jeans when I have been the same size for 2 years. My last period was march 23. I'm so confused on what to think and could use some advice!!!!
