I had a miscarriage for the second time in april, at 11 weeks. My periods have been irregular since up until just recently. i had my period around 3 weeks ago as normal lasting the usual 5/6 days. around a week ago me and my boyfriend had sex, we started off un protected, then used a condom. again in that same week we had fully un protected sex. In the last couple of days ive felt alot of the symptoms i felt in my last pregnancy, bad headaches, slight cramping, feeling sick nearly all day every day, being tired even though ive slept for hours, odd dizzy spells and just generally not feeling quite right. could i be pregnant?
