My last period was nov 17. So my period is 24 days late according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a>. I took 6 pregnancy test up till today and they all came out negative.Today,January 8 I started bleeding. Heay cramping to the point I had to take a ibuprofen for it and slight blood clot. But my bleeding was able to kinda fill one tampon second tampon didn’t fill. And when I wiped nothing came on the tissue. Which is weird to me because during a normal period of mine Im able to fill the second one. Now I’m wondering if this is implantation bleeding or a period ? Any help/information would be great!!
