Period to start on dec 11

Ive got sore breasts and have been having terrible migraines and nauseous as heck. Ive been trying to have a baby but am so nervous. Ive lost 4 babies and 1 last year i was 20 weeks. I do have 2 children a 4yr old boy and a 6 yr old girl. Would you stop trying and just let go of trying to fill that void? My kids want more siblings but they dont quite understand the pain it puts us through trying and failing. I just want a healthy baby to add to our family! Should i give up after so much loss?
