Breastfeeding with tubular breast?

i have gone through hell to continue to breast feed. this is my third child. with my first two i half breastfeed and half formula feed. they were fine with switching back and forth. i have tubular breast. they are spread far apart and are almost all aureola, and are long tuberous shaped. i saw a lactating consultant with my first and all they told me was to pump after each feeding and keep trying. it was to hard to do and i was only 17 when i went trough it the first time. now i am very determined to breastfeed. for the first 3 weeks i was trying to breastfeed exclusively but my daughter was not gaining any weight so i started half and half again. after i had a surgery complication and was hospitalized for 2 weeks and i pumped and dumped every 3 hours i knew i want to keep at it. i got about 24- 26 oz a day while pumping.. my baby was 2 1/2 months at the time. she is now 3 1/2 months and for about 2 weeks she has been refusing the bottle when i go to work and leave her with my mom she fights her to not take the bottle ( she loves the breast) i even got her breast like nipples.. but she only wants to breastfeed. yesterday i breastfeed her all day and she seems content.. no crying other then right before she goes to sleep in the late evening. she is having many wet diapers but no poop yet (she pooped 2 times the day before yesterday). even though i have been maybe 70% breastfeeding her for the last 2 weeks. i have been taking fenugreek 4 capsules 3 times a day trying to increase my milk and i think its helping a lot. im just worried that she isn't getting enough.. since she refused the bottle.. and i don't know how much milk im making now.. could she be ok since she seems happy and normal even on breast alone? or should i continue to fight her to get her a bottle or two a day? need support.. please
