one night I had some spotting which i believed to be the start of my period but it was very light and went away again(happens sometimes as my period is slightly irregular as it is and always fairly light for the most part), i was drinking this night and started to have unprotected sex with my boyfriend but we stopped fairly soon into it as we realised it was stupid and he didnt ejaculate. The next morning i got the emergency contraceptive just to be safe and i got my period the next day and it lasted longer than usual. About a week or two ago we were having sex using a condom, (we usually are very careful that time was a once off , regretted it straight away) after we were finished my boyfriend jumped up quickly this caused the condom to be pulled off him while it was nearly out of my so only the very top part of the condom remained inside and the rest was totally outside, i was very careful in removing it making sure nothing came out or even touched me . i was 100% sure at the time that nothing came out because it was practically out and i was careful. Im waiting to get my period now its around 4 days late but i feel like i should get it as i have some symptons.
Im just wondering if this is caused by the emergency contraceptive i took at my last cycle, my periods arent always realiable at the best of times. Im really stressed out and scared about this and would appreciate any insight on this.
