advice?

Hi ladies, just a quick one. How long after taking the pill should you start having sex again? I take the pill where you have 3 weeks worth, and then have a 7 days 'period'. ( I say this in '' as I only ever bleed for like 2 full days) so Monday just gone was when I was allowed to start my 3 weeks of pills again but I was still having a little amount of bloody discharge when I went to the toilet. I was hoping I'd deffo be off as I was seeing my long distanced boyfriend who I haven't seen for a good 3 months😔 so I desperately wanted to have sex with him. ( I'm not horny all the time lol, I don't mean to sound like a sex pest 😜) long story short, we had sex as I hadn't bled for at least 6hours. He didn't cum inside of me but I had only been taking my pills for 2 days at this point. I'm just concerned that there maybe a possibility that I could get impregnated. I have taken today's pill also if that counts?🙈 any advice will be appreciated!😞
