Im not sure if I'm starting my period or spotting. I know the only real way to know is to just wait it out but hopefully someone can help me here. I had a period 9-16th October then sex on the 27th October. According to the Flo app on my phone that date was high chance of pregnancy but I’m not sure how accurate that is. I forgot to log the last couple of periods, last one I logged before October was May, plus my periods are odd-for the last year or so I’ve had period every other month instead of every month (I think had a period in July but not 100% sure) . Anyway, yesterday evening I had some spotting which I thought might be the beginning of my period (as maybe they’re going back to normal again as my last period was a month ago) my breasts don’t feel tender but they feel heavy and I had cramps but they felt different to usual period cramps but surely can't be pregnancy related as i wouldn't have cramps this soon would I? I still haven't come on my period and normally would have by now after spotting. I've bought a cheap test and not sure when to take it. How do you know when to test if you’re periods aren’t usually monthly or regular?
