Hey there..
I had the sore boobs, a few pimples i usually get a week before my periods is due and constipation.. I fell pregnant while on the pill. My period for the past few months had been jumping between a few different days so i was thinking perhaps thats what happened. I was 2-4 days over due (because of the jumping around dates) and wondered the same.. and i was a little paranoid to walk into the chemist to buy one as i never had to ever before.. but i thought bugger it.. im going to get a test! Least then i knew whether i was or wasnt then and there, rather than thinking about it and waiting any longer.
Its your choice, but theres a chance that you very well could be? My fingers are crossed for you!
