TTC # 2 after using fertility treatments with # 1

[mjbj]

Hello! I'm a new member! My husband and I have a 6 month old and are now TTC # 2. We are on a clock because I we're both in our late 30's and I'm taking time off of work to raise our (2? potentially) kids until they go to prek. I am currently nursing my first and have had 2 cycles so far- 38 days apart. I did OPK for this cycle and it showed a + yesterday so we did the deed lol yesterday am, night and will again tonight. I used to have a 28 day cycle regularly and ovulated day 14 PP but naturally, nursing is causing my cycles to be off. I belong to 2 breastfeeding support groups and wanted to join a TTC one to share advice and experiences. Right now my question is about sperm. We hadn't had sex in a about a week and then had sex yesterday am with the + OPK. Will those sperm be a dud since they my husband hadn't ejaculated in over a week? Was the sperm last night not rejuvenated? I hope we didn't miss our window this cycle. So much to do with timing....TIA!
