Does anyone have anything similar ?

I had my period on August 5 till 11 and after that my breasts start to feel tingly and hurt and I have chronic back pain and I also was feeling sharp little pains in my abdominal area in middle I don't know why I gets this cause it's almost similar to early pregnancy signs . But even before I started my last period I had symptoms like I was pregnant but still had my period and now I'm having symptoms again don't know what to expect I'm gonna see a doctor next month cause that's when my card is effective and I'm going to concieve this time but it strange to have symptoms and not be pregnant ? And. Of course I start stressing which I shouldn't so please ladies give me good advice please and prayers please .
