Missed period twice, spotting, but slim chance of pregnancy, maybe?

Hi I need help.
I am 19 yo going on 20. I have a fat body not some skinny girl. My weight is around 72kg. My boobs are big, 36D.
Last year on February, my period took a very long time like two weeks with the first week really2 little blood then the second week a lot of blood. My mom took me to a gyno and there's nothing wrong with me. I took birth control pills on December but i didn't eat it normal. Missed few hours or forgot to eat one. My period came on January and it was the worst, I bleed heavily, blood cots every wear. I had to change every 3 hours or I would bleed through my pants. 5 days later my period stopped. On January 28th, I had my cherry popped by accident with some guy's finger.

I spotted on the mid of February but missed my period.

On February 25th, I played around with a guy. I remembered he had precum on his penis and I blow job him for a few minutes. Then in a missionary position, he humped me. I was naked and so was he. The thing is I didn't know if he penetrated me or not because his penis was small so I had doubts. He said he didn't go in but he was a jerk so I didnt know if I could trust him. He came to my mouth and that was the last time I played around with a guy.

I missed my period on March and April. I don't feel nauseous. My breast feels the same, not tender or sensitive. My clothes feel the same, I eat normally. My stomach looks normal but I'm not sure it is bloating or pregnancy thing. Please help!

I would like to know about mine. My bf and I messed around last March 2017 but it didnt enter inside me just brushed without clothes on. I'm having my period regularly for 3 months now and they are all normal, for 4-6 days and I think I'm about to get my 4th this June 2017. My belly was always big so I don't know. Is it possible for me to get preg?

I'm on the pill and have had my periods for 4 months now with normal and flow and on time but I keep having pains and feel bloated can I still be pregnant? I had sex when I took a pill one hour late then a few weeks after I had sex on the last day of my 7 day break please help put my mind to reat

Hi, ive read your situation and i was thinking if you could help me out. I don't know if im pregnant or just bloated. Ive read some of the symptoms online and i have none of those no nausea, vomiting, discolored nipples, etc but i don't know if its just weight gain

Can I ask a question?
About three months ago I had a sexual activity with my bf and he just rubbed his penis over my vagina with my panties on. He said he did not cum. Is it possible that I can get pregnant through this if ever a tiny bit of semen went out?
Cause right now I feel like somethin's moving around my tummy. But I had my period the last three months. Each period lasted for about 4 days. I kinda feel like my tummy is getting bigger and somethin is moving like how I feel when I am hungry. Is it possible that I am pregnant?
