TTC #3 and questions!

Hey everyone! I’m Danielle. I’m 30 years old. My husband and I have been married for 11 years. We have an 8 year old son and 9 year old daughter. We are TTC for #3. I had a miscarriage in April 2018 at ~8wks and a chemical pregnancy in May 2018 with 3 positive UPTs but betaHCG was 0 two days after my positive tests. My cycles are about 35 days. I’m on CD18 with predicted ovulation on CD22. I started having EWCM on CD16 and we BD last night (CD17). I haven’t tracked this stuff since my first pregnancy with my daughter. Is EWCM really a strong clue to ovulation? My body is so different now compared to when I tracked before. I’m plus-sized now and my cycles used to be ~30 days and very regular. In addition to the ovulation question, anyone else adding 1 more to an already “established” family?
