Good points above. If not tracking ovulation you just want to BD every other day. Look into supplements for yourself and him. You can also try to track ovulation with cervical mucus and/or cervical position if you want to.
If this is how things are now, imagine what they could be like with your baby. Take care of yourself, you deserve kindness and patience. Smoking can be harmful in any case. 🤍
Firstly, if your period is always between those times, you have a regular period. Irregular would be if someone had 32 days one month then 76 the next and they were all over the place. Secondly, if your partner is blaming you for not being pregnant and is creating an issue but not willing to make any changes himself, I’d highly suggest you rethinking having a child with him. I know it’s a frustrating time when you’re trying and nothings happening but you need to have someone who will support you through all of this. If they’re not supporting you now, it’s highly likely they aren’t going to support you through pregnancy, post partum & parenthood. Unfortunately there’s no quick fix for falling pregnant. As rubbish as it is, you can never guarantee a pregnancy
