Please help

I would seriously appreciate any responses because I usually get none on here. I am 20 (please keep rude comments to yourself) and we’re wanting a baby (husband and I ) I have been stressing myself out so bad by the thought of fertility issues. I have heavy period the first 3 days and pretty bad cramps the first day that subside into moderate ones the next day or so. Sometimes it can be painful during sex but I feel as if it’s because my husband is hitting my cervix. And I do get cramps after I have an orgasm but not bad (I know tmi). And sometimes I get super light little pinching cramps through out the month after and before period nothing serious. My question is has anyone else experienced this and was fine? I have a pap scheduled to rule out a few things. I jist have been so stressed out.
