13 weeks pregnant

Hi Mummies. This is my second pregnancy. Currently 13 weeks pregnant. Isit normal to still feel cramps and keep farting?? My morning sickness was quite bad since day 1 of the pregnancy till around week 12? It started to get better but sometimes I will still feel sick…. For my this second pregnancy I am quite anxious about it and always wanting baby to grow well hahahaha. Everytime appointment day me and my husband will be very excited to see baby and happy to see that baby is growing well. We just seen baby few days ago… btw when can we find out the gender? I have forgotten.
