When I got pregnant and June I had clear symptoms that told me I was pregnant. I miscarried in July and ever since then my PMS symptoms have been like pregnancy symptoms... my last period was only 3 days.... usually I get PMS symptoms on around cycle day 25 with a 31 to 35 5 day cycle... on cycle date 17 I started to get cramps and sore boobs.... that's so soon to have PMS symptoms....
