UPDATE please helppo

Original post:

had sex during my fertile window... he wore a condom however he only went in and out a few times. And after each time he did check the condom the make sure it wasnt broke, the last time he went in and out it got a little tear (so we know it happened on that thrust) he did not ejaculate in or near me. And I took plan b. (But I hear now it doesnt work if you’re in your fertile window and have already released eggs) fast forward! I had some spotting before my period and then the day before it was due i got a heavy flow for 3 days. And then it got lighter which isn’t that uncommon for my cycle. A week and two days later (today) I took a test to be sure (this would be 23 days after sex) and it came out negative. Should i stop worrying!?

UPDATE: today at 23 days after sex i have cramps and diarrhea.... is it just a sickness or could i be pregnant
