I tested on Tuesday and got a faint positive and AF arrived the day after. Only it lasted 2 days instead of 4 and only filled half my cup. Since then I've had back ache on one side and period like cramps that seem to be getting worse. Went to the GP today and she booked me in for a scan to check ovaries and everything and did a PT but came back negative (I'd just had a wee before hand) what could be causing this pain? I feel like my periods about to come! My boobs are heavy and sore I don't get it?
