#AskTheExpert Hii Mam.. I'm having 5yr old baby.. I'm trying for second but couldn't..4 months back i had d and C in early trimester due to no heart beat, doctor suggested me to wait for 3 period cycles.. already 4 cycles completed.. My last period was on Dec 31.. my period cycle was 30 days.. but this month I got period today after 43 days.. I'm having hypothyroidism with tsh 2.8 (as per last month report) using 50mcg from past 2 yrs.. So can I conceive or not ? why this late period happened?
