23 weeks pregnant and horrible insomnia

Any one else suffering for this ? Passed 2 weeks I have had horrible insomnia last night I fell asleep at 12 and woke up at 3 and couldn’t fall back to sleep so I cleaned up the whole house :( I tried taking Benadryl and sometimes it works and sometimes it doesn’t . Last night was not a good night ! I have a two year old so I feel so guilty when I’m so tired the next day . Any advice here I’m at a loss . Going to my doctors on Thursday and I’m going to talk to them again about it
