So I 16F and my boyfriend 18M had our first intercorse on 27 May. Let me get it straight Im very paranoid and anxious and I want an opinion on what we did and if by doing so I couldve actually became pregnant. So on 27 May me and my boyfriend first touched our selves unprotected and tried to put it in but he could'nt (also to mention he pissed before hand and wiped so he didn't have precum on it) and we both didn't finish that time. Afterwards on the same day we tried to have sex again and he tried to put it firstly without condom then when he felt like he was about to pre-cum he put a condom on and we finally done it. After we took a good glipse to see if the condom broke which it didn't because only my blood was dripping from it. On 28 May we had full protected sex , by that I mean he used the condom all the way and it wasnt broken either. Then on 29 we touched eachothers private parts and and he came then wiped himself with a tissue not touching his hand and he continued doing me. I also took a pregnancy test on 29 May and bought ellaOne (the morning-after pill). I did the pregnancy test in he morning and came negative and for the pill I took it on 30 May for insurance of not becoming prengant. I should mention that my period also came on 29 May a bit later then when I took the pregnancy test and it changed too like usualy id get heavy bleeding and a lot of painfull cramps but now everything was lighter from the blood flow to the cramps. My bleeding is also a ton of colors and I don't know why (brown,red,pink) and everything usualy goes in the toilet then in the tampon. Id be very happy if i get some opinions in what I've done good or not and what are the chances of getting pregnant from all the things I said and the main question Should I be worried?
