Late period.. help!

[watermelonsugar11]

Hi,

I'm late on my period by 6 days now and I'm confused as to what's going on. I'm not on any contraception but we use condoms religiously, all my pregnancy tests I've taken have been negative but I'm just not too sure what to think of it all. I've been getting really intense back pain, sharp pains in both my sides as well as sharp pains across my pelvis, I've got my usual breakouts on my chin what I normally get just before my period, increased discharge, feel very nauseous, extremely tired and just like complete and utter crap!! Just for reference, my cycle for the past 8 months has been completely spot on every time so I'm so baffled! Pics of pregnancy tests I've done over the last few days x

Have you been unwell or under any stress lately which could have delayed your period?
id try take another test with fmu and if still negative you could always check in with your gp and see if they
will do a blood test for you.

I haven't been unwell or that stressed recently, a lot more chill than I normally am I'm not on any new medication or anything like that! I will re test in a few days and if still no luck I will contact my GP! Thank you :)
