Missed pill, HELP!

Hi, I am on microgynon 30 and have been for a little over a year and a half. I take it everyday around the same time. My last period started on June 1st and started it back on the 5th June. On the 9th of June (I think) I had diorrhoea and stupidly didn't take another pill. On the 11th I had unprotected sex with my boyfriend, this never usually happens so I was put off pretty quickly and stopped, he did not *** inside me. I know I was stupid in not taking another pill or using a condom but I completely forgot I even had diarrhoea until two days ago. Should I take another pill now? I've taken them everyday since but I'm not feeling well at all. I dont poo everyday (sorry) but from Monday until Friday I pooed every single day which is unusual for me which makes me think something may be wrong. Usually when my period is here I do go to the toilet a lot more so I'm thinking maybe that one day where I may have lost the pill my body thinks it was a break? I've had cramping but no blood. I'm freaking out at the fact I could be pregnant but it's too early to know so will hold out until the withdrawal bleed. Anyone ever experience anything like this or have any advice?
