Missed period

Kristy
I miscarried about the middle of November at 7 or 8 weeks. I didn't find out until a month later at routine check up. A week later I had d & c. January 14th I had a 4 day period. Skipped a day and then had a day of bleeding again. I am now one week late. Possible conception 2 days before missed period. Took pregnancy test at home 2 nights ago and it was negative. Lately I have had bad acne. Headache for 2 days, nasuea late night and dizziness. Anyone else had this?
