If you have been trying to conceive and you feel lost and have not been taking ovulation tests, please do so!!! Me and my friend both ovulate about a week later than the app was estimating!! Her cycle is very is irregular. She is now pregnant after 5 months of trying. I have just started this month to try for my second baby, my app said day 11 but I have been taking ovulations tests for a few months and it’s actually on day 18 consistently. I have a 31 day cycle very regular!
