Camping everyday since 1dpo?

I ovulated CD16 on May 12th. I know this because of my bbt chart. I had intercourse everyday of my fertile window. I'm 7dpo today and everyday since 1dpo I've had light cramping that is bearable but it's definitely there. I felt a few twinges as well in my uterus that feels a bit like vibrations. Been very gassy today (tmi sorry) had a few days of constipation and keep getting hot flushes. Temp rose very high this morning for the third time since ovulation. Yesterday at 6dpo my breats began to feel very sore and are today also. But are these cramping a and signs pregnancy symptoms? I know it's unlikely as I'm only 7dpo but I have never had cramping 7 days in a row especially straight after O. Any ideas? Is this a good sign? Thanks in advance
