I was taking althea pills since may. Then after 7 days off, I started a new pack. But on july15th me and my boy friend had sex and that was my last pill. Because I was afraid that I will be pregnant after taking the last pill, I bought a new pack and took the first pill. Then took the 2nd pill on monday july 24 , after the 7 days off instead of taking first on sunday july 23 because I already took the first pill on july 16.. Then took the rest of the pills correctly after that. But again, me and my boyfriend had sex about 10mins after taking the last althea pill. Should I worry of being pregnant? It was my third and last pack of pills and I dont want to continue anymore taking pills. Please help me figure it out. Thanks.
