I just told my ex that we might be pregnant and he said how do I told him because I just woke up because I went to sleep at 2:12 and I woke up at 2:52 and he said that is not long and I said if this continues imma take a pregnancy and he said ok then and I said this is serious and he said ok. What should I do?
