TTC question...please help!

So my husband and I had sex on Saturday and Sunday. I've been taking ovulation tests in the morning and yesterday I got high ovulation and this morning I got peak. We just can't do it tonight. Just so tired!!! Monday's are horrible for us. Since we had sex Saturday and Sunday do you think we are okay? I really hope so! Going on 4 months of TTC and although I very much enjoy sex with my husband I hope this is it! I appreciate any insight! Thank you!
