I don't get it.

I’d also really like to share my story. Maybe someone here wants to take a look with me. I stopped taking the pill on March 10th. I did this consciously, and therefore I consciously wanted to get pregnant. I had sex with my boyfriend from March 10th, almost every day. On March 15th or 16th, I had a light pink bleeding that lasted only a few hours. I already thought I was pregnant back then. At the end of the month, I took a test and I wasn’t pregnant. Later, I had a test done at the hospital and then I was pregnant. On May 27th, I went to the gynecologist who asked me for the first day of my last period. I didn’t know because I hadn’t really had a period after stopping the pill. Well, they did an ultrasound. It turned out I was 10 weeks and 1 day along. The heartbeat was completely fine. The gynecologist said I must have ovulated on March 30th, and from that day on, I counted a bit myself and it would have taken 4 days for the egg to implant in me. Is that possible, or does implantation always take longer?

Also, I was quite sad because I work in the sex industry and it went wrong 2 times with the condom. That was on March 23rd and on April 5th/6th. I can rule out the second time because I was already pregnant then. But could it also be that the sperm stays in me for 7 days until an egg is fertilized? (I should mention that after the guy pulled out, the condom got stuck inside me and I pulled it out, so maybe there was no sperm in me) but I remain unsure about it. The gynecologist says my due date is December 21st. I myself calculated 9 months from when I had a light bleeding on March 15th, which would put my due date on December 15th. If my due date is December 21st, I can also calculate from March 21st to December 21st. That’s also exactly 9 months.

I don’t understand the gynecologist’s calculation at all. How do you count from April 3rd (implantation) to January 3rd as 9 months, and then my due date is December 21st? I don’t get it. Maybe someone wants to help me and take a look to ease some of the uncertainty.
