Am I out if FRER comes back negative at 7/8DPO?

I'm currently 7, MAYBE 8DPO. I'm not exactly sure when I ovulated, but I had a very positive OPK on the 22nd and my fiancé and I dtd that night. We weren't able to dtd any other time during my fertile window as he went away to a training course for work the next day and was gone for four days, damn him Grin. With my last pregnancy I fell pregnant after having sex once during my fertile window, so it can happen for me! Though that was the pregnancy I lost Sad

I took a strip test today (not with FMU) and got what I think is a very very faint line, but I then took a FRER a couple of hours later and it was negative.

I'm beginning to think the 'positive' strip test was actually an evap, even though the line was pink. FRERs are supposed to be more sensitive than strip tests so why would a strip test be positive and an FRER negative?

Am I out if a FRER comes back negative at 7/8DPO? Is there any point in testing tomorrow with FMU?

Thanks! Smile

No! They only work 6 days before you miss your period and the day you miss your period is the day after your period should have arrived. I think only 60% of women gt a positive before then. I did cave and do a FRER this month but i'm now just going to wait until a few days after my period like I did last time.

Leave it a couple of days before you test again.

There’s information with your FRER that it’s not 100% accurate this early. It’s around 75% I think? The closer you get to your period, the stronger the line will be.

Also, your HCG doubles every 48h so definitely worth waiting a couple of days to catch that if you think you had a squinter today :)

Fx for you!

Absolutely not! For all the stuff about how early they can test, I’ve had a bfn on a frer at 11dp then a bfp at 13dpo.

I’m sorry for your loss and wish you every luck Flowers

@User12879923378, ah, my period isn't due until the 6th of June, so I guess it was pretty pointless taking one today... I just couldn't resist! Grin Thanks to both of you. I guess I'll leave it at least two/three days.
