Nausea after miscarriage

Je

I had a blighted ovum and naturally passed it at 10 weeks. Saw the Sac and everything. Bled heavily for one week and spotted for an additional week. Now my CM is starting to return to its normal sticky/creamy state. TMI... Sorry. My husband and I have had unprotected sex without much concern because I was taking ovulation tests and they all came up negative. HCG tests are still negative, latest one as of yesterday. It's been about 2 and a half weeks since I passed the Sac and doctor cleared my miscarriage. However I have had strong feelings of nausea (specially after eating) for about a week now. Something that I didn't really deal with during my pregnancy. Is this normal? Think it's just stress and hormones balancing out?
