This is where i say patience is a virtue. Maybe just maybe they are planning a surprise...... And if that is not an option then ask you mom. I had 4 kiddos and 4 showers.
Try getting the god parents involved and ask your husbands advice too he could hint to his mom or his side of the family . Hosts for my showers were
1st =my mom & dad
2nd=my mom & dad + the god parents
3rd=my husband had a surprise one
and both sides pitched in
and did it potluck style
4th=a family friend offered and then became the godparents
send an e-mail and so maybe you don't really need anything then throw one for yourself and add to the invite that all gifts will be donated to single mothers.
This is when you can have a raffle of some sort . Wine basket, fruit basket, sports stuff, candles.
Good luck and god bless.
P.s. With all the $$ you will save by not throwing yourself a shower you could do a spa day or gift youself or your baby something you would normally not buy yourself
