I had a pregnancy scare a few weeks ago because my period came a little over a week late on March 6 (the last time I had sex was in early January, but I had a normal period 3 weeks after near the end of January). Although I was relieved when it finally came, it was a very unusual period. It was MUCH lighter than my period normally is and I had two huge chunks of what looked like my uterine lining show up in the blood. The period lasted for 5-6 days and was light the entire way through, which is extremely unusual for me. My cramps were bad for a few hours, but that's pretty standard. Is this strange period a sign that I might have had a miscarriage? Also, even though I've had two periods and two negative pregnancy tests, I'm worried because I've been feeling nauseous these past few days. I know I'm being anal, but I would appreciate some advice!
