hey I'm 19 years old and cannot stop worrying about being pregnant between November and January I was a bit reckless having sex without a condom whilst on birth control pill. I'd been sick after drinking then had sex but many hours after taking my pill. I haven't had sex since mid January but am so worried I could be pregnant. I haven't missed any periods and they have been normal, no symptoms really apart from sore breasts before my last period which went after and I've taken multiple negative tests. I've had some funny feelings in my tummy but I think it's where I've been worrying. is it likely I'm pregnant? or am I just being irrational?
