I’m 26w1d with mo/di girls. I’ve felt a lot less fetal movement today than normal and my stomach has been rock hard. I’ve felt jolts of pain that shoots down thru my vagina on and off today at work. & I’ve had back pain which I’m sure is just from walking at work. I was able to check heart rates with my fetal Doppler, & they sound fine but I’m just curious if this is normal?
