Plan B / Period

Soo I had sex on October 11 we used a condom but what had happened was we had a total of 6 condoms... 3 ripped but he never came so we used the 4th one he had tooken that one off because I thought he came and I didn’t see for stupid!!! he was making himself in the mood .. so I wasn’t paying attention I was just fixing myself But I never seen him change the condom and I thought he did soo we had sex again and then that’s where I realized because at the end we used the last 2 condoms and he came in those two so I told him wait did you reuse the 4th condom and he said yes and I told him why at first an argument cuz never reuse a condom!!!!!! And I told him did you come in that one and he said he didn’t remember but he thinks he had it backwards and blah blah with the lies then started laughing so I got disappointed!!! So the next day I decided to take the Plan B just in case he did because he had it backwards and just in case he came in that one and for him laughing cuz I didn’t for check stupid! As well!!! But for extra protection I last a whole week with effects than the last time I took which was in April...... I’m not sexually active at all!!!..... but these effects hit me more than anything than last time soo I was like wait what if I never needed it because i had all the effects of the pill except vomiting I never vomited so I was paranoid idk why it just got me this time and yesterday I spotted blood is this a sign of my period coming or should I wait to test and yes I know this is crazy weird and dumb but don’t come at me we all adults here soo I need good respectful way responses about this!

Edit: I started my period!! October 21, 2020
