Pregnancy like symptoms after miscarriage

I had a very early miscarriage in December. It was my first pregnancy. My periods returned in January, but since then I've had intense pregnancy like symptoms between ovulation and my period. Tender breasts. Nausea. Headaches. Fatigue. Intense mood swings. This month I'm three days late with a negative test. I never experienced anything like this before the miscarriage. I 've never have any pms symptoms other than a little bloating and cramping.
