Confusing symptoms

Emily

So for five months me and my partner have been trying but always been on the wrong days... Since I got this app it has been so helpful, now I'm needing some advice if that's okay.

I would have normally have had my period on the 19th May, it was three days late and was only spotting when I actually had my period and had mild cramping at the time, it only lasted a day and half the spotting. I've done several tests but have been negative. I went to see my GP and explained everything to him but he was a little confused. He has now booked me in for blood tests.

Am I reading into this too much?

Thank you all for any advice x
