7 weeks pregnant unsure about the conception date

[newmama91]

Me and my boyfriend were planning on having a baby as we both felt ready and it was the right time. I was going to start using ovulation sticks and read on the package that you're supposed to start using them on day 14 with a 28 day cycle.

My last period was on the 15th of March. On the 24th I had unprotected sex with an ex which my boyfriend now knows about. This was a mistake.

On the 27th I used the ovulation stick which was negative but me and my boyfriend decided to have sex anyway. I used the OP stick a day later which still came back negative.

On the 4th of April is when I got a very faint line on the OP stick. We had sex the day before.

My clearblue pregnancy test came back positive on the 14th of April stating I was 2-3 weeks pregnant on the test which on the leaflet states it means I was 3-4 weeks pregnant.

I'm just wondering if there is a possibility I could have ovulated earlier in my cycle instead because the pregnancy test came back positive quiet early or if the ovulation sticks were wrong?

If the pregnancy test said 2-3 weeks that means it was 2-3 weeks past conception. So sounds more likely that you conceived around 27th. Have no experience of ovulation sticks. I think you will struggle to be 100% certain though.

Depends on how long your cycle usually is? If 28 days then ovulation would usually be around 29th March, but if you have shorter cycles could have been earlier.

Ovulation sticks don't show when you ovulate, only a hormonal surge which may precede ovulation. They can also show as positive when you are in fact pregnant so the faint line on the 4th is perfectly likely to have been because it was actually picking up the pregnancy as opposed to ovulation.

The conception indicators are roughly accurate and atm, all you have got is a rough idea of when your baby was conceived. You should have a slightly clearer picture when you have your first scan. Sadly, it looks likely that you conceived some time in the week that you had sex with two different men. I think you will find that you won't know who the father is without a DNA test.

Guessing using faint ovulation test positives and the rough approximations of a pregnancy test isn't going to help in this situation.

If you slept with one on the 24th and one on the 27th you have no way at all of knowing whose it is. Forget all about the test stick or trying to work out dates, anyone who tells you here hasn't a clue either. You don't ovulate at exact times every month, and sperm can last varying amounts of time before fertilisation. There are far too many variables for such a short window.

DNA test is the only way.

[Grantaire]

The length of your cycles probably won't help either given that the luteal phase (time between ovulation and period) is considered normal between 10 and 16 days. It sounds like you're not sure about your own cycle so you could have a 28 day cycle but have ovulated on various dates within that.

I'm afraid you probably can't know with any degree of certainty.

I assume that it's the sex with two different partners which is throwing up the question of dates? Apologies, if I've misread.

[newmama91]

No you're right. I've been completely honest with my boyfriend and he is being very understanding and supportive which I don't take for granted. But it is still on my mind a lot.

My last cycle before that was a bit weird. It lasted from 7th feb to march 15th. Before February I used to almost always have a 28 day cycle.

You'll be unable to tell from dating scan etc and realistically with three days in between it could be either. Sorry. With my dating scan they put me at conception date which was impossible. Dna is only option.

[PurpleSwift]

With 3 days between them you have absolutely NO way of knowing who you conceived this child with until it is born and you do a DNA. All you can do until then is guess.

[PurpleSwift]

Also sperm can live inside you for up to 5 days. There's a very real chance you had both men's sperm in your body when you ovulated which is whybitbis impossible to tell with a DNA test.

[PurpleSwift]

Why it is impossible to tell without a DNA test**

[ejclementine]

The clearblue tests aren't always 100% accurate either as they go by the amount of hormones in your wee. I'm 5 weeks and clear blue came up 2-3 for me.

[sianihedgehog]

I had several dating scans which moved my dates around by nearly 10 days. The only way you'll know is a DNA test.

[boatrace30]

Sorry - I misread and thought one of the times was the 15th. As other posters have said, you'll have no way of knowing, especially as sperm can survive for up to a week (though more likely 2-3 days) so you could have conceived via either partner days after you DTD.

[slightlyinsane]

I'm a 28 day cycle but ovulate ealier in the cycle, anywhere between 9 and 12 days. Unfortunately everyone on here is correct and dna is the only way forward.
