I had my periods on 13th of last month then on the 20th me and my boyfriend decided to hv sm fun as i helped him cum and after i wiped da cum off my fingers with a cloth then after he also helped me feel good by touchng ma clit.after like 3 to 5 mints i used the same hand i used while help him cum to chck my virgina lips to see whether i had become wet or not.i didnot touch inside my virgina but i just touched out side like for 6-7 seconds then i removed my fingers.the next morning i had creamy pinkish and waterly sperms in my nikers. reading different articals really made feel nervous its now 2 weeks past and have no signs like they state them except that my nipples color skin is the same colour as it was before except that the black colour has extended a little on my breast.very little i feel no single pain in my boobs however much i hit them but still i hv noticed some bit invisible strech marks developing around them.could i be pregenant?
