7 DPO....symptoms?

Brittany

I am 7 DPO. On 4 and 5 DPO I had cramping and backache. I still have some very faint cramping and lower backache a few times a day but not constant. Also, my CM is thick and creamy. Are these symptoms? My temps have stayed high so far. I also get sick to my stomach when eating certain things. I 5 DPO I got a terrible headache. Any input appreciated! Thanks!
