<human>: Can you succinctly summarize the text in 1-3 sentences?

My girlfriend and I have started having protected sex recently. I've only ejaculated twice and both times have been outside of her and inside the condom. Once has already proven not to be the cause because she had her period after the first time. The second time was while her period has been late. We have had sex without me ejaculating a total of probably 3 times. She has recently missed her period and it has been a total of 14 days. We're both a little worried but I am trying to be reassuring. Could anyone give some advice to put my mind at ease?
