Really hun, u shunt have unprotected sex, i ddnt and im still pregnant, and i was on the pill! Im only 16 too. Well, the only way u can truly find out if you are pregnant is to take a test, ya mite not wna bt ya have gotta!
The fact that u had a very short period at the wrong time, straight after unprotected sex may have simply been implantation bleeding, which it most likley was, so that wud mean u was pregnant.
Fine out and keep me posted yh? We’ll go thru it 2geva
Much love x.x.x
