My last period was November 13th and my next period was suppose to have came on yesterday but it didn’t. My partner and I did not use any protection last week. I’m also on the combination pills which I started that pack on December 3rd (Had a break off birth control pills for 3 weeks). But I’ve missed two of them! Could I be pregnant? I was suppose to have waited after 7 days for the pills to be in my system to have sex so I could be protected. My period is regular and it is always on time! I’m very worried.
