Yes it help thank yall so much lady's ..!!!!
It's never easy to calculate exactly as it depends on the length of your period and also the length of your luthal phase. If you had an average 28 day cycle you would have approximately ovulate on the 30th March but it means you could have conceived from probably 26th to 3rd of April. And it could be give and take a few days regarding ovulation.
Does that help?
Count back approx 38 weeks. I believe that would put it in the last week or so of march. It's impossible to tell the exact date really
