Hi, in this pregnancy, did you have an early ultrasound? If so, could you dig it up and look at it? The dates that would help answer the question you have are what week GA they thought you were at the time of the ultrasound (you'll see it in weeks and days), that is their estimate of the time span from when your last period began to the day of the ultrasound, and especially, your estimated due date. If you get an estimated due date from an ultrasound in your 6th, 7th or 8th week of pregnancy, that might go a way to answering the question of whether the guy on the 5th or the guy on the 10th is more likely to be the dad.
The reason this can't be answered simply from the Plan B point of view, is that if the sex with the guy on the 5th (for which you didn't take Plan B) was one of the times Plan B didn't work (the 1 out of 8 figure), you could have gotten pregnant and been pregnant by the time you had sex April 10, (the time you did take Plan B. Plan B won't knock out a pregnancy once it is in place). But there is nothing wrong with calling the Plan B answer line, if they have one, and talking to them.
Well based off the babymed that says the sex that could of helped in convincing the baby was APRIL 5-april 10 saying those were my fertile days....I had sex w someone different both April 5 and April 10 for April 10 I took a plan B pill but for APRIL 5 I didn't my question is an I pregnant from the 5th or the 10th
What do you mean by "the first day of ovulation" and "the last day of ovulation?" Ovulation is the egg popping out of the ovary and beginning its journey down the fallopian tube. It is a one-time event.
Unfortunately, even the Plan B literature says Plan B does not work 1 out of 8 times. The fact that you got pregnant means it did fail.
I take it that you are wondering if you had sex a certain number of days apart (I still don't get what timespan you are thinking of because there is no such thing as a first day and last day of ovulation, but anyway) and in between the two times you took Plan B, you're wondering if that would mean the first time was the one that took and the last time would be sloughed off by the Plan B. Depending on how many days were in between the sex, it might be an interesting call to make to the Plan B question line.
