my last period was on june 6th...it was within the span of june 23rd thru june 26th that my boyfriend and i had protected sex twice and the condom was put on properly and didn't break. The following week i was on a mission trip in Washington D.C. I left on the 27th. im from a small town in ohio...would the different environment and travel affect my body to make my period late? also the past few days before i went on my mission trip i worried about possibly being pregnant for no reason really, it was incredibly stressful to me. The only reason i can think that i was pregnant was because before engaging in intercourse we were hugging so that our genitals were touching but not so much that he was inside of me...it was only for a few minutes and at the very beginning. or could the stress of feeling pregnant afftect my menstrual cycle?
