Is My Fantail Pleco Pregnant?

So ive been trying for about 3 weeks now to get my two Albino's to Breed...payed 30$ for each of the two so put in ahout 60$ for the breeding pair into this project and have yet to see any type of results till a few days ago, my female has been "Plumping" up a bit but I still cant tell if shes pregnant or not. here are a few pictures of my Male just to show ya how he looks lol and a picture of my females stomach.

what do you guys think??

Either that or shes extremely well fed. It's impossible to tell but she looks like she might be full of eggs. Good luck.

Cool..I really havnt seen ither of them eating much at all lately, most of there food does not get eaten as far as ive been noticing, before, they were eating reallllly good and now they have seemed to kind of stop but pick at the drift wood more and eat what ever is growing on the driftwood we cant see with our naked eye which i know they do a lot. that driftwood was outside in the sun for a good month and i just threw it back in the tank after letting it dry out so im sure something is nice and ready to be eaten off that thing, they have both been stuck to it but usually when there nice and full there stomachs are black and hers is hardly black but still getting thicker as far as ive noticed. will be my first pleco breed if it happens, going to just end up moving the babys to a 20 gal and let the parents keep breeding over and over and just moving babys over and over and then migrate them over to my 80 gal and see what happens after a while, i have 3 other albino bristlnoses in my 80 gal that are normals not the fan tail versons so maybe going to try and cross breed and see how many fan tails i get out of those two
