So I thought my period started, and I’m entirely sure if it’s actually a proper period

Typically my periods are 3-5 days and really heavy on the second day

Both today and yesterday, basically I’ve had one gush of bright red blood and then that was it. The rest of the day was basically nothing.

When I say ‘gush’ I meant like I felt something bubble out so I went to the bathroom & there was a blob of red blood (yesterday), and today I went to the bathroom & sat there as there was a long line of blood dripping out of me.

Other than that there has been little-no bleeding. Is this a period?

Had sex in Jan

I used a condom & he also withdrew before he came (did NOT finish inside me)
