I just realized that I messed up typing that.. I ment to say the difference between the 2 periods apps is that app 1 says I was fertile the 16th-21st and doesn't tell me when I ovulated the other app says I was fertile 16th-22 with ovulation being on the 21st. Again I understand that apps aren't doctors and don't know your body. But maybe fixing that and adding that in there would change something?
Hi, are the dates you name as "the 5th," "the 16-21st," etc. July dates? If so, make an appointment and get an ultrasound now. Tell your doctor that you aren't sure when your last period was, or that your cycles are too irregular to use them to date the pregnancy, and that you want an estimated due date (EDD) based only on the baby's ultrasound measurements and growth markers. When you get the EDD (don't let them send you home with just a number of "weeks pregnant," that won't help), put the estimated due date into a conception calculator and it will give you an estimated conception date. (Or just count back 266 days from it, on a regular calendar.)
Don't delay, since you're officially now (if the dates you are talking about are July) about 5 weeks 5 days since the first day of your last period, and ultrasound information is the most useful if it comes from your sixth or seventh week (again, counting from your first day of your last period). As the pregnancy progresses, it gets less and less accurate. (By the time you're in your 40th week, it can be three weeks off!) But if you get an ultrasound this week or the next, and if you get your due date (again, not just "weeks" but the actual date they think your baby will come), and the due date is based on your ultrasound and not on when your last period came, you should be able to get an estimated conception date.
I hope that it either indicates the 14th or after the 26th, because in the middle, you will have had live sperm in your body from both guys at the same time, since sperm can live 5-6 days. If your ultrasound does put you in the middle range, the only way to know which sperm met the egg is by a DNA test. They can be done by a blood draw from you and swab from the men, but those prenatal tests are really costly. Otherwise, you'll have to wait until the baby is born.
If this is the way it happened, after a period starting on July 5,
14th guy A
16th guy B
19th guy B
21st guy A
26st guy A
Positive test 31st
the only thing that would rule one of them out is if an ultrasound told you the 14th or if it told you after the 26th. (If it told you the 20th, you could try to extrapolate that the baby came from guy B because all of guy A's sperm would have been dead from the sex on the 14th, but that is asking for a certainty that ultrasounds can't quite offer.)
If your menstrual months are regular and only about 28 days long, not super short nor super long nor irregular, then the odds (unfortunately) are that you ovulated when you had living sperm in your body from both men at the same time, since sperm can live 5-6 days in your body.
Your ultrasound can give you a date of conception but it can't tell you which sperm made it to the egg if your ovulation did fall into a time when you had different guys' sperm in your reproductive tract. So though it's good to get one, you're only doing to see if you get lucky and it says you conceived on the 14th or the 26th or beyond. (Though I will say, the 26th or later would be surprising because you had a positive pregnancy test on the 31st.)
If you find that the ultrasound puts you in the middle ground, you might contact Ravgen or the DDC to find out how much a prenatal DNA test costs, I've heard various prices from $1500 to $2000. (Don't go with an Internet cheapie so-called "lab" or you will just be throwing your money away.) Test with BOTH men; one guy's positive will reconfirm the other guy's negative, and vice versa. If you can't afford that kind of test, the only other option is to do a DNA test after the baby comes, which are a tenth of the cost of the prenatal DNA tests.
As you can see, mama told us not to have unprotected sex with more than one person in the same menstrual month for some good reasons. Along with everything else, please get tested for STDs.
Good luck!
Thank you. I've already been tested for stds and I'm clean. With guy B we actually used condoms both times.. but the second time after we had sex. He took the condom off after he came then we did it a quick second time so I could finish and he ended up coming a second time but not much came out and after we finished I didn't have any sperm leaking out or on me. If that makes any since and that happened on the 19th. With guy A everything was unprotected. Not sure if that would change something?
Hi Anniebrooke I told the doctor that I didn't know when my last period was, So they did an ultrasound and only based it off what the baby was measuring and the baby is measuring 6 weeks 5 days. Which date would that best indicate when I conceived?
