Positive test followed by 3 negative tests

[user1488903347]

I took this test on Saturday and within minutes this clear line appeared, obviously I was excited so I took another test which was negative followed by another 2 negative tests [emoji30]
My period is due Saturday but this has really confused me.
I've been on anti-biotics ( which are safe as I checked ) and been put on folic acid tablets around 1month ago as my iron was low.
If anyone has any advice or past experiences i would be very grateful.

Unfortunately you've posted in the wrong topic - Site Stuff is for techy issues with the MN website.

There is a Conception topic on here www.mumsnet.com/Talk/conception where you'll probably get a lot of support, help and advice. It might be worth re-posting in that topic - or asking MNHQ to move this thread over.
