Low sperm count and FET

Gal • 32, TTC #1 for almost 4 years, IVF in December 2015, MC at 5 weeks; FET in July, waiting for beta on 8/2! ☺️
Hi ladies! I've had an <a href="https://glowing.com/glow-fertility-program">IVF</a> last year in December, MC at 5 weeks. We decided to take a break from everything and maybe ttc naturally. Meanwhile, my husband took some fertility vitamins (low sperm count and mobility) and he went for a bloodwork yesterday. I was so sure the results will be better.. They weren't. The mobility increased but the actual number decreased. I just got a positive ovulation test today so I'm not giving up yet! I have a histeroscopy scheduled for June, but I still want to ttc naturally until then. I don't know if I'm being crazy but today's my birthday and instead of celebrating, I'm just crying because of these results, because it's been 3 years since we started ttc, because I'm 32 and have no kids yet, because I give all my love to my dog and cat.. I'm so tired, girls.. I'm going to do the FET in July and pray to God for my rainbow baby. Anyone here done a FET? What treatment should I prepare for? Will I still have to get filled up with hormones? Thanks for reading, ladies.
