So my s/o and I had sex on dec 20th and it is now the 23rd, ever since I’ve been having really bad heartburn and today I started getting really crampy over what seemed like my left ovary. Yes I am well aware of it being wayyyy to soon for me to be pregnant, but I was wondering what my chances may be. I had my period this month from the 9th to the 15th and according to this app my fertile window started on the 19th and on the 20th it said that my chance of pregnancy was 15% but the highest I’ve ever seen it go up to is 33% so if 33% is the whole like 100% does that make the 15% really like 45-50%? I’m so confused and I don’t know what to do. I bought some prenatal vitamins because even if I don’t end up being pregnant I hear that they make your hair grow. Can anyone give me some advice and help me out? Do you think my chances of becoming pregnant are high?
