Is it normal to be on your period, but not really?

Like, I've always had an irregular period. I started puberty at 7 around the time when they recalled the steroid milk. Anywho, now my period is regular...... and irregular. It comes every month, yes. But it doesn't last long which is normal for me. It usually last 1 - 4 days. Recently, I have been taking some diabetic medicine and unknowingly I had went off my period for a full month and as soon as I stopped taking it, I got my period back. SO! I'm on my period now, but not really. Meaning, I don't have to wear pads nor tampons because it's not coming out on my panties, however, it's only coming out when I pee. Blood clots and everything. It's kind of concerning.
