im 2 days late. and ive tested positive on tests. but im having like the dull aching like pre af cramps. ive had them for like a week now but im starting to worry since ive had several miscarriages. is it normal to have this? im also having some nausea, extremely sore boobs, and fatigue. so im having other signs of pregnancy. thanks for any info!
