23F, So I made a naive and stupid decision this weekend by having sex without protection during my fertile window. For reference, I have a very regular cycle that lasts anywhere between 26-29 days, and my period lasts 6-7 days. I use the Flo app to track my cycle, however I have never tracked my ovulation using home tests before, so the estimates are purely from the app's algorithm.
My timeline for the month:
-- 10/10 period started
-- 10/16 period ended
-- 10/18-10/24 my predicted fertile window
-- 10/22 my predicted day of ovulation
-- 10/24 the day I had unprotected sex
First, we had sex without a condom until he finished on my stomach. He pulled out with enough time for nothing to end up inside of me at all. Then he went to the bathroom, peed, and washed himself off with soap and water and we took a break. Then we had sex a second time, except this time we put on a condom. However during the middle of it, the condom slipped off and got lost inside of me, and had to be fished out. He did not ejaculate at all the second time, so my main concern for this entire night is whether or not his precum can make me pregnant. I do believe I was still in my fertile window as I was plenty wet/had EWCM.
The morning after on 10/25, I took a plan B one step. It caused me to have some nausea and cramping but I feel completely normal since.
My main concern is whether or not I had been ovulating during the time I had sex. If I ovulated days before, and the egg had long disintegrated, then I had no risk to begin with. If I ovulated the day after having sex, then the plan B hopefully extended my ovulation long enough for any sperm inside me to die off. However, if I had sex during the 12-24 hour window of ovulation, then the plan B will not help at all and I could get pregnant.
I have no clue when I ovulated, so I'm afraid the plan B will just end up being useless. I have an appointment scheduled for tomorrow (4 days after sex) to get a copper IUD, however I'm also nervous that this too will be pointless. I'm probably done with ovulation by now as my discharge has dried up and I no longer feel horny/aroused as much, but that's just my guess.
I'm just so afraid that even after I go through the pain and potentially traumatic experience of getting the copper IUD that it will still be for nothing because my egg may have already been fertilized. Everything I've read online states that the copper IUD is not necessarily proven to prevent implantation, and that its main function is preventing fertilization. What if I'm already past that point?
I am completely torn apart over this and could use anyone's thoughts or guidance. I know that he never ejaculated in me at all, so my risk lies in whether or not his precum contained any sperm, so that hopefully helps my case. And I know I made such a stupid mistake that I never will again, but I need to know whether it will really be worth it to get this procedure tomorrow. I'm so afraid it's too late. Anyone with a similar experience that can share?
