HELP 😭

Olivia
me and my boyfriend have only tried sex twice. He only got half of the way in, and then pulled out. I also bled for a little and had to wear a panty liner the rest of the day. The second time, he got it in all the way and thrusted like a few times, but then pulled because he could tell I was in pain (I know we need lube now) and he panicked because he said he could feel some precum come out. I also bled more than the first time and had to wear a regular pad for the next day or so. the color of the blood wasn't the same as my period blood. I have also been a little stressed over this situation. I don't know what to do, and I'm only 17, I went ahead and got the pill, and my gynecologist said to start it on the first day of my period, but that still hasn't come yet. Very worried teen here.
