On june 1st my partner and I had sex and he ejaculated in a condom. He took it off after and there were no holes. He tried not to get semen on his fingers but then he lightly wiped his fingers on a tissue. He wiped the front of my underwear for about 10 min. Then fingered me after. Later when I realized this mistake we purchased plan B and I took that in under 20 hours. June 1st was a day before my 3 most fertile days. I later had heavy bleeding and cramping on June 18th. 2 days later than when I expected my period to come. Making this a 34 day cycle. Could I be pregnant ? Its been almost 5 weeks since the incident and I am having nausea and breast pains when my period is 2 weeks away
