Help!

Ronnie • Nurse Mom to a little boy Baby #2 on the way

So I got a positive Digital OPK on the 10th. BD on the 9th and 10th. Yesterday has some slight cramping and bleeding. It seems to have stopped this morning but it was enough for me to use a tampon for good measure. Not sure if I’m starting my period early or what. I’m so confused and hurt because I thought this was it 🥺 note that it was for maybe 2-3 hours
