This happen to anyone else?

The start of my last period was 1/8/15 , this is my first month TTC. My next period is due on 2/5/14 and since about 4dpo I have been having bloating and cramping. For the past four days by the end of the day I'm very crampy and have bad lower back pain. This is very unusual for me. My breasts are also usually very tender at this time but are not sore at all. I have noticed my nipples are very sensitive but they do not hurt. So I guess what I'm asking is has anyone had these symptoms before getting a BFP?
