cycle

Hello there! I've been TTC for 8 months although in the beginning we weren't actively TRYING per say, I had just stopped taking the pill. I have been taking the pill for 12 years and figured it would take a while for my cycle to regulate as prior to BC I was not regular. For 5 months my period was very regular (28 days), now not so much. In the last 4 months I've been tracking in Glow regularly and keeping my awareness up regarding ovulation. My last cycle was 62 days and I had a lengthy period (9 days) which is not usual for me. I had spotting for 3 days 2 wks after my period but it was not implantation (said 3 pregnancy tests). I'm now on day 52 (neg test 4 days ago). I just bought ovulation strips but do I need to wait to get my period to start taking them? I heard there's an OTC medicine that helps bring along your period- is this okay to use? Any recommendations? I'm starting to get a little nervous... thanks so much!!
