I'm pretty sure I ovulated around the 7th of Aug. Ever since then I had cramping, sometimes kinda bad. Now it's the 15th and I had a blood clot this morning. I'm not due for my period till like the 22nd-23rd. I've had spotting before BUT NEVER a blood clot. There's been a little spotting since this morning, BUT not much. Is this something I should maybe be worried about?
