Re: what is meaning of T3,T4,TSH in medical terminology. Thyroid levels can have various impacts on pregnancy and getting pregnant. Also, thyroid levels tend to jump around a bit following pregnancy. Yours is a bit elevated, which doesn't effect the baby as much as low thyroid levels can.
Cartilage ear piercings may take up to a year to fully heal, but generally take 3-6 months (as opposed to the ear lobe, that takes just 4-6 weeks). They heal from the outside in, so even if it looks fine on the outside, you should not assume it is fully healed.
I'd say that for the daith, as with any piercing, you should wait until it is fully healed. Daith piercings, as any other cartilage piercing, can take as little as 3 months to as long as 12 months to fully heal. It ultimately depends on the thickness of the cartilage, how fast your healing is, how well did you maintain it clean, how well did you prevent infections, and other factors.
