Hi I take the pill ridgevidon but am currently on my 7 day break form the pill, however I have yet to start my periods. I had a period 4 weeks ago when i was on the previous 7 day break form the pill, so this was in december. But before my 7 day break in december i was on antibiotics and totally forgot that they prevent the pill from working, and had unprotected sex 4 times, even though I had a period a week after this occasion could I still be pregnant now due to the fact I haent had a period this week? Please could could you in form me, Im getting worried. I cant afford to pay but i need to know
