My last cycle was 9/24/20 to 9/27/20. the cycle before that was 9/1/20 to 9/4/20. on 9/5/20 my husband and i had sex...i had irregular bleeding 10/5-10/6...i have felt nausea, headaches and fatigue...is this stress or pregnancy?

Pregnancy worries?: It can be hard to guess whether a woman is pregnant or not. A urine pregnancy test gives a reliable result by 3 weeks after sex (3 weeks after when conception might have occurred), 1 week after missing a period, or after having a "weird" period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon. Can call (video) primary care doctor if questions.
