Plan b

lydia

So I have my periods regularly. On the day I ovulated (sept 10) I had sex and did not take a plan b. Exactly a week later (sept 17) I had sex again but I got scared and two days later I took a plan b on the 19. I had sex on the 20th and again the 23. Late last night (24th ) i started spotting ( exactly 14 days).

Then today I had cramps and blood like a regular period but the blood on the pad is light when I’m normally really heavy my first two days. Do you think by me taking the plan b on the 19th messed up my chances of getting pregnant? Or should I still test?And I definitely want to have one next month so what should I do besides having sex on day of ovulation.
