I'm not a woman...hope it's okay to ask something though. My girlfriend does not take birth control due to allergic reactions, so I use condoms. I have vowed never to not use a condom because we don't want kids. Long story short we have done withdraw from time to time and even though I am very well in control of myself (if you know what I mean) and withdraw with time to spare, I worry that I got her/will get her pregnant. She's been having stomach pains for the past 2 days and don't know if just her feeling bad or if it's something of concern. Just looking for some input from somebody. Thank you.
