Is there any chance I'm pregnant?

Hi. I am on the combination pill and I take it every day. Before I started taking the pills, on January 21st I got fingered by my boyfriend who in all honesty could have had semen or precum on his hands. I felt slight cramping on the evening of January 26th, which was supposed to be the time I ovulated according to the calendar. I got a light period on February 10th, it was two days of full bleeding then three of spotting, which is unusual for me. I was under stress the week prior to my period, so I figured that was why. I started my pills on February 26th, which is when Is supposed to be ovulate again. I took my pills perfectly on week one. On week 2 of my pills I took the pills a few hours late on day 2 and I took them a few hours late on day 3 as well. Every other day that week was on time. On the first day of week 3 I touched my bare vagina just a little bit after touching outside of my bfs boxers. I also touched my vagina from outside of my clothes when I was giving my bf a handjob. I was wet and so my shorts and underwear we're moist. On day 2 of week 3 I took the pill a few hours late. I am really worried I got pregnant. Yesterday (which is week 4, day 3 as I take the pill nonstop) is about 9 days after that happened. My boyfriend was fingering me yesterday but that started to hurt, so then he switched to fingering my bum which we did without any sort of lubricant and we did it for maybe 10-15 minutes. My bum hurt a little bit, but we kept switching it up a little so it didn't hurt as much. After we were done with that I went to the bathroom, wiped, and saw that what I wiped was ever so slightly pink. I of course freaked out thinking "THIS MUST MEAN I GOT PREGNANT AND ITS IMPLANTATION BLEEDING!!" so I wiped again and there was nothing. Then I wiped just me V and it was normal, then just my bum and there seemed to be the ever so faintest trace of blood possible. I talked to my boyfriend afterwards and he said while he was fingering my butt he thought he felt poop or something as it got a little wet he was doing it, then he thought it was just sweat. However, when he cleaned his hands, he said he saw no blood. When I got home, a few hours later, I wiped again and there was the smallest amount of pink. Lately I have been having the faintest cramps right above where my hip joins with my leg, like where I would think my tubes are, and my boobs are hurting. Also, I've been tired. Could this all just be from the pill? I am really not ready for a baby yet and that's why my boyfriend and I don't actually have intercourse. Is there any remote chance I'm pregnant? I don't have access to tests, I'm too young...
