My lmp was on January 2 I had sex with my bf every day from the 6th to the 11th January then went went out of town an I had sex with my ex on the 12th of January now I'm pregnant the doctor says I'm 6wks 2 days. I'm really worried who would the father be?
You will need a DNA test. There is no other way to tell, the dates are just too close together.
You had sex on days 4-9 of your cycle with your boyfriend. You had sex on day 10 with your ex.
You normally ovulate sometime between days 11-16 of your cycle. Sperm can survive up to about 5 day - max. The egg is viable for up to about 48 hours after ovulation - max.
Fertilization is not immediate. It can take several days. Your doctor, no one, can not tell when you ovulated after the fact.
Sorry. You can take a "non-invasive" DNA test as early as about 9 weeks.
Your doctors date does not make sense. It works back to January 16, as of today. It's off by 2 weeks from when you know your LMP started. Most doctors base how far along you are from your known LMP. Ultrasound dating is not reliable.
