I Give Up

I'm 26, and we've been TTC for the last 8 months now with no luck. Is it time to get ourselves checked for fertility issues? I did get pregnant 5 years back with my current partner but we took the hard decision of having an abortion at that point (Please don't judge).

I do opk tests + bbt + CM checks and have a regular 28 day cycle, and we've been timing the BD well. I also take multi-vitamins though my partner does smoke.

I don't know what else to do😭😭
