It's been 7 days till the beginning of my period. Today is the last day. Although, I've been feeling a swollen abdomen, and under the belly button, in the uterus zone, I just felt it was swelling too. It's been swelling 21 days ago, 2/3 days before my ovulation. Along with this swelling, my breasts increased, increasing the same day my belly/uterus felt swollen. I think it's relevant to say my period seemed normal to me, with a normal amount of blood and intensity. My question is: what are the possible causes for this swelling on the uterus? I feel no pain, it's just that swelling.
One more question: this may be a bit dumb from myself, but I've masturbated with my boyfriend 25 days ago. No fingers inside my vagina and he just touched me with his hands. He cleaned them before touching me. I was afraid I was pregnant before of that (I've read on the Internet it's possible...) but my another question is: as I menstruated, it's not possible to be pregnant, right? This swelling has nothing to do with it, right? (I just read some stuff on the internet as well that there were some situations where some women menstruated till their 5th month of pregnancy... so, here's why I'm asking...)
Thank you for your attention
