Advice on a touchy subject

So me and my boyfriend live together along with my 5 year old daughter I’m currently 11 weeks pregnant with baby #2. Anyways when my boyfriend moved in 2 years ago he brought baggage 3 dogs I already had one. So we have a 3 bedroom house with a little yard. I feel bad because I’m pregnant and have been in and out of the hospital with Hyperemesis. I got discharged and came home today to find the house trashed dogs been using the floor as the bathroom. My boyfriend works 12 hour shifts and I was in the hospital so it’s not like he’s the blame. But I’m overwhelmed with all the dogs now more than ever because I’m pregnant and sick, and here in another 6/7 months I’ll be bringing home another baby. I don’t want all the dogs it will be way to much and I feel terrible and selfish feeling this way but I just can’t handle it especially being in and out of the hospital and my daughter spending days with her grandma. How would I bring up a solution that won’t break my boyfriend heart but helps me not stress out about it all anymore.
