So I m 25 years old. I had a baby last April, and breastfeed for 4 months because after that I couldn t produce enough. I stopped at the end of August. I got my period back September 8th. (Same as before I got pregnant.) typically my period lasts 2-4 days. I had sex on September 30, with no protection. I had some bleeding on October 8th. I don t exactly remember how long it lasted. (At least 2 days.) I m not sure if I had sex anymore that month besides the 23rd, which I used the pullout method. Well, I had a positive pregnancy test on November 8th. I went to my obgyn, they scheduled me for an ultrasound and I was 13 weeks and 4 days (putting me at July 9th) Which is 6 days ahead of what my LMP suggested that I was due. (July 15)Ever since then, I ve had 3 more ultrasound all within 2-3 days of the original ultrasound date. When s the likelihood that I got pregnant?
