Give up or not....?

Ever since my daughter was born 2 years ago I have always had unprotected sex with my husband, fell pregnant and 10 weeks later (mid August) I had a miscarriage and had a D&C.; Doctor put me on birth control for one month to regulate my period again (it worked). After that we been ttc ever since just to get 1 false positive early December. I'm giving up ttc since clearly it's not working but yet again 30 min after I say this I'm looking at apps, looking through internet for tips, Amazon ovulation strips, etc. Should I just give up or what?
