I really need advice..

So I had my first baby back in August. At my 6 week appointment I was never checked down there. I was also scared to feel or look down there myself 😂 A few weeks later i finally did and realized my lady part doesn’t feel the same? But eh just had a baby so wasn’t too worried about it. Few months go by and it gets worse. I had this one episode where I was struggling to pee and felt a buldge coming out... I was like “ok somethings not right!” Well now I’m pregnant again.. I’m 21 weeks! Two appointments ago I had my OB look there and told her I feel a buldge.. she looked felt and asked if I had any pain where she was pressing and I replied “no” because I didn’t. She then told me everything looks fine? And that was it. But now here I am sex is even MORE painful, the pressure down there is so much more severe, I am litterally peeing my self fully anytime I sneeze (which imma having bad allergy’s right now also) and most days I feel super swelled down there.. some days the lumps out even more then others. I find nights where I just cry because idk what’s wrong with my body, and it’s effecting my relationship ..

So i guess I’m wondering does this sound like a prolapse? And now I don’t even know how to bring it up to her again without feeling embarrassed or crazy..

Any advice will seriously help! I just wanna hear from others who can relate if it sounds like a prolapse may be what it is..
