Query on periods. Is it normal?

Hello there, I had some private moments with my partner last month 13 th to be specific with the date , he used double protection and we didn't do it all in as in it didn't enter the vagina ..it was all outer. But i felt some liquid on my thighs but according to my partner his Siemens didn't spread out and was inside the condoms itself and according to him it didn't break as well.In a fear of doubt and to be secure I consumed a pill the very next day early morning empty stomach 14 th August to be specific.After consuming the pill I puked a little later , don't remember exactly when but I did.I get my periods usually last week of every month in 20s but the last month I got my periods on 22nd but it remained for 1 day which I consulted by practo doctors and they confirmed it's normal but to be sure I took several urine n blood test even all were negative, this month I got my periods on 18th itself and a heavy flow remained for 2 days.
