Hi I am 31 year old, planning to conceive within a month itself, Please guide me. I have hyperthyroid taking thyronorm 75 mcg daily. I have a regular menstrual cycle of 30 days. Also suggest me a good sperm friendly lubricant that would not disturb me in conception. Currently I am using vaseline and it is very comfortable, I use it in the outer opening only and some on my husband, would that affect us in conception or is it fine. I would be comfortable with olive or canola oil rather than other medicated jelly. Please suggest.
