I've been having mild RL pain since 7 weeks. Sometimes it really feels like someone is stabbing me for a moment thought. So I feel your pain (literally hehe). And yes, when you are coughing and sneezing a lot, it makes it worse!
Kegals are your best friend for reducing pelvic pain. It's especially helpful to do a super-tight kegal just before getting up from a sitting or lying position (which is typically when pelvic pain is the worst).
