Likeliness of pregnancy????


I got this app and even bought premium because I want to know when I’m most likely to be pregnant, not to get pregnant but to better avoid it?!? I don’t want my boyfriend to panic thinking I’m trying to get pregnant and I love the community. But I’ve had it for three months now and it still has nothing for pregnancy %%????? How do I find out when I’m most likely to get pregnant on this app!
