How is a thin womb lining thickened???

Womb lining thickene. LebogangM ~ usually under the influence of hormones. Estrogen thickens, progesterone in the 2nd 1/2 of the cycle makes it mature and allows breakdown. Pregnancy and infection and neoplastic conditions are some others. Do not worry about this. All you should be doing is seeing the OBGYN once a year for an exam and a PAP smear and he will advise if any problems.thx.
