I was using Bio Oil at the start of my 2nd trimester. A week later, my belly started getting realllllly itchy and little red bumps started appearing.
DH got an aloe vera plant from his coworker and he started extracting the gel to apply to my itchy belly every night. A week later, wahh la la... no more itchiness and red bumps are all gone!
I read that eating aloe vera is not recommended during pregnancy because it causes the uterus to contract, but external application is fine. Just throwing it out there for other mama-to-bees who are experiencing itchiness. The aloe vera plant only costs about $20-$30 but it's a lifesaver!
