I had a period on around October 2nd, then had sex on October 19th. A condom was used. I got another period on around October 24th. I am not sure if I was ovulating because I can be irregular at times. My last period was on November 23rd. This month it is late by 5 days and I have been under stress due to finals and also flew and traveled somewhere for vacation. Yesterday, I asked my partner if the condom had broke and he said no. I am going to test in the morning and hopefully I see it is negative.
