My wife and I have been trying for about 5 months to have a baby and so far no luck but this month things seem different. She had her period on 16 June 2018. When she woke up to bleeding and it was normal flow and red but on 17 June it was very light and 18 there was nothing! Her flows are always 3-5 days. Did she just have a random one day period or could she still be pregnant? I am so confused.
